Abstract
The Fermi energy in semiconductors can often be freely controlled across the whole energy gap by doping. This is not the case in oxides, where different mechanisms exist, which can limit the range of the Fermi energy. These limits can be caused by
i) dopants having deep rather than shallow charge transition levels,
ii) self-compensation where the Fermi energy dependence of the defect formation energy leads to spontaneous formation of compensating defects,
iii) the change of the oxidation state of either the cations or the oxygen.
The latter is particularly relevant for compounds with transition metal or rare earth cations and has been recently demonstrated to explain the low water splitting efficiency of hematite. It will be demonstrated how the limits of the Fermi energy can be assessed using X-ray photoelectron spectroscopy (XPS). The variation of the Fermi energy can thereby be achieved either by deposition of thin films on different substrates, by deposition of differently doped films, by different surface treatments including oxygen and vacuum annealing, oxygen plasma treatments and water adsorption, or by formation of interfaces with low and high work function metal oxides. Extensive data sets for various oxides, including dielectric, semiconducting and ionically conducting materials are available. The effects will be illustrated using selected materials and the importance for different applications will be discussed.

18-06-18, 2:00 pm: Colloquium - Prof. Dr. Joerg Schaefer:
'Novel Nanoscale Quantum Materials – From Design to Spectroscopy'

 

On Monday, 18-06-18, 2:00 pm

Prof. Dr. Joerg Schaefer
University of Wuerzburg, Experimental Physics IV


is holding a presentation on the topic:
"Novel Nanoscale Quantum Materials –From Design to Spectroscopy"


Abstract


Today, the quantum properties of a large range of materials have come into focus, because this reflects back onto the electronic and optical properties, and their application potential in terms of electron transport and computing. The underlying quantum physics becomes particularly apparent in nanoscale materials, where, e.g., the Coulomb interaction between atom starts to play a role, or when two-dimensional (2D) materials are realized that have specific spin transport properties. At the very heart of such studies is the epitaxial growth of materials with atomic scale control, which allows the realization of artificial material architectures that would otherwise not exist in nature. We will present an overview of several such designer materials. The high-resolution spectroscopic inspection by scanning tunneling microscopy and angle- and spin-resolved photoemission allows a full account of their electronic properties. By employing local spectroscopy with the tunneling tip, one can even detect the conduction channels of interest spatially resolved.


Key representatives include 2D electron systems grown on semiconductor wafers where one can control the degree of electron correlation, and the resulting conduction and spin properties. A second and very modern class of materials are topological insulators – which carry metallic conduction states at their surface, separated by spin character and inherently protected against defect scattering. These materials exist as bulk systems with large-area topological surface states, as photoemission data can illustrate nicely. With a perspective for applications, recent developments of 2D materials are particularly intriguing: when a graphene lattice is mimicked by very heavy atoms, specifically bismuth, one can generate a Bismuthene monolayer supported in an insulating substrate [F. Reis et al., Science 357, 287 (2017)]. It is a wide-gap quantum spin Hall insulator which exhibits protected conductive edge states at the flake boundaries – a candidate material for room temperature applications. The talk will present a perspective of the possibilities and challenges of such novel approaches for electronic quantum materials.

Abstract:

The talk will give a brief introduction to optical generation of tailored strain pulses and monitoring of coherent and incoherent nanoscale deformations in solids. In particular, I will discuss applications of tailored strain waves for synchrotron pulse shortening and coherent control of surface phonons. In the second part of my talk, I will discuss temperature dependent deformation of so-called air-gap heterostrucutres. The thermal expansion coefficient of the structure is determined by static XRD measurements and shows a strong deviation compared to properties of the bulk material. The unusual thermal expansion is reproduced in time-resolved XRD and optical reflectivity experiments.

"Probing Structure to property relations of single semiconductor nanowires"

 


Abstract:

Semiconductor nanowires, including core-multi-shell nanowire heterostructures, grow in the cubic zincblende and/or the hexagonal wurtzite phases. Due to their different structural properties, these crystal phases can possess different physical properties. Here, we demonstrate the direct correlation between the structural and electrical and optical properties of several single core-multi-shell GaAs/In0.15Ga0.85As/GaAs/AlAs/GaAs nanowires grown by MBE onto pre-patterned 111 Si substrate. Due to alignment of electron beam lithography drilled holes along a single line, it was possible to access individual nanowires and to investigate both properties in as-grown geometry. The structural phase composition of single nanowires was revealed by synchrotron beam assisted X-ray nano-diffraction. The optical and electrical properties of the same NWs were extracted by home lab cathodoluminescence measurements and measuring I-V characteristics by a focussed beam equipment.

Prof. Dr. Brice Gautier

INSA, Lyon


is holding a presentation on the topic:

"Nanoscale measurement of the electrical properties of ferroelectric thin films and crystals for the control and the engineering of domains and domain walls"


 

Abstract:

The goal of the presentation will be to present the research topics and past work from our INL team, in connection with ferroelectric materials, and also perspectives for the future. I will focus on results obtained with Piezoresponse Force Microscopy especially on the influence of water on the electrical properties of thin dielectrics and apparent growth speed of ferroelectric domains. Then I will switch on the limits of the PFM technique and development of new ways to assess ferroelectricity at the nanoscale based on current measurements. Eventually, I will present our projects around the control of ferroelectric domains and conductive domain walls.

Several words about the team :
Francis Calmon and I are the leaders of the "electronic devices" team of the Institute of Nanotechnology of Lyon. The team aims at studying and developing new types of transistors, memories and sensors in close collaboration with people involved in the microelectronics (including industrial partners like STMicroelectronics). My own work focuses on near field microscopies, and more precisely on the electrical measurement at the nanoscale using techniques derived from Atomic Force Microscopy (especially Conductive AFM, Piezoresponse Force Microscopy etc).

"Gravitational-wave detection and the role of 100kg-sized
crystalline-silicon mirrors"


Abstract:
Heavy high-quality mirrors that are suspended as pendulums are a key ingredient of gravitational-wave (GW) detectors. All GW detectors today use Suprasil 3001 as the mirror substrate material. Future GW detectors will use cryogenically-cooled crystalline mirrors, most likely made from crystalline silicon. The international GW community, which consists of more than a thousand researchers, is highly interested in know-how about minimizing the optical absorption of crystalline silicon bulk and surface between 1.55µm and 2.1µm. We aim for less than a few ppm/cm, and an absorption of superpolished surfaces down to below 1ppm. Solving this challenge will strongly push the realization of the next-generation of GW detectors such as the European Einstein Telescope.

"Enabling tailored molecular thin film growth through in-situ x-ray diffraction"


Abstract
Applied physical research on soft matter thin films based on small organic molecules has been a vital field in the past decade. Nowadays a significant share of research on organic thin film structures is attributed to new deposition techniques and the quest for additional growth control parameters in order to follow surface-by-design approaches. Besides the choice of the molecular specials employed in the organic thin film its functionality crucially depends on the structural properties which are in turn a result of the employed growth process.
In this talk a novel strategy to fabricate organic thin films with tailored structural properties is presented. More specifically, the impact of dynamic temperature oscillations on structural thin film properties is analysed in depth. These temperature oscillations are employed on the time scales of molecular monolayer growth. X-ray growth oscillation (at the anti-Bragg point) are used to trigger rapid thermal cooling cycles during the nucleation phase of each individual monolayer while growing the organic semiconducting molecule PTCDI-C8. Using in-situ grazing incidence small angle x-ray scattering (GISAXS) the enhanced layer-by-layer growth of the thin film is analyzed in real time. Following the concept of two motilities the island density is strongly increased during nucleation diffusive processes are selectively enhanced at later stages of mono-layer growth. Based on analytical growth models and phase field simulations the interplay between inter-layer transport and the size of molecular islands is analysed to shine light on kinetic processes during growth defining the surface morphology.

MAL GANZ GRUNDSÄTZLICH: PROTEINE

We are surrounded by proteins everywhere: in the supermarket on the nutritional value tables of the food or quite obviously in protein bars on the muesli shelf. But Proteins also play an important role in our bodies and perform a wide variety of tasks there.

Moderator André Lampe will welcome Janine Kirstein, who is very familiar with the topic. Why she is an expert is not revealed in advance and is part of the concept: only at the end of the evening is it disclosed whether Kirstein is a nutritionist, scientist, physician or something else. The audience is invited to ask questions before and during the event. A small protein experiment will be presented as part of the warm up.

The event is also the first live recording of the audio PodCast “mal ganz grundsätzlich”. During the conversation, live artist Roland Brückner illustrates and projects his impressions on various surfaces in the room.

09-06-18 / 5:00 - 12:00 pm: Long Night of the Sciences

 

  Long Night of the Sciences at the Leibniz Institut for Crystal Growth  

Crystals are the hidden heart of many of the technical solutions we meet in our everyday life. They are essential for modern lighting, computer technology and data transmission, they enable the generation and storage of energy. Special applications require crystals with precisely defined properties, for example for the detection of radiation in space or the redefinition of the kilogram scale. We show their development, characterization and processing as well as the corresponding growing technologies

"Progress in BaSnO3-based Materials and Devices"


Abstract:
A wide-bandgap perovskite oxide semiconductor BaSnO3 was recently found to possess high mobility and excellent stability. Its single crystal mobility value of about 300 cm2/Vs in the doping range of 1019~1020/cm3, when n-type La dopants in place of Ba are used, is the highest among all the semiconductors. Furthermore, the oxygen diffusion constant in BaSnO3 was measured to be several orders of magnitude lower than other oxides, demonstrating superb stability of the material.
Taking advantage of such properties, excellent field effect transistors were recently demonstrated using amorphous gate oxides (AlOx and HfOx) as well as high-k epitaxial gate oxides such as LaInO3 and BaHfO3, which led to development of an all-perovskite transparent high mobility field effect transistor. In addition, p-type doping by K in place of Ba is feasible and the pn-junctions made with K-doped BaSnO3 and La-doped
BaSnO3 were demonstrated to exhibit near-ideal IV characteristics. Moreover, 2DEG behavior is found at the polar interface of BaSnO3 and LaInO3. We will go over the parameters that control the 2DEG behavior and discuss the mechanism behind such behavior.
In spite of these tremendous progresses, the device performances are currently limited by defects such as threading dislocations. Once all the major defects are removed, the perovskite oxide semiconductor BaSnO3 system, especially when it is combined with other perovskite oxides, is expected to offer much more opportunities for science and technology.

"Group-IV semiconductor nanostructures for optoelectronic device applications"

 


Abstract
The application of Si to optoelectronics is limited due to its indirect bandgap and the concomitant low efficiency in optoelectronic applications. Alloying Ge with Sn can lead to a direct bandgap group-IV-material if the Sn content is high enough, however, the lattice mismatch of ~15% makes the growth of binary GeSn alloys challenging. The ternary alloy SiGeSn enables decoupling bandgap and lattice constant and is, therefore, an interesting candidate for optoelectronic device fabrication. The use of nanostructures composed of both GeSn and SiGeSn alloys could potentially facilitate the growth of Sn-rich, direct bandgap semiconductor layers and offer additional degrees of freedom in order to tune the bandgap as well as enhance optical properties as a result of carrier confinement in one or more directions. In this talk, the fabrication of GeSn and SiGeSn quantum dot and quantum well structures based on molecular beam epitaxy as well as their characterization will be presented and applications in optoelectronic devices such as photodetectors or refractive index sensors will be discussed.

Abstract

Since the invention of the first bipolar transistor, integrated circuits have evolved to incredibly complex, ultra-scaled devices with on the order of 109 transistors per chip. Even if these devices no longer rely on bipolar technology, excellent control of highly doped regions is still a critical factor for device performance. Moreover, single dopant atoms in a silicon crystal or nanoscale silicon transistors are thought to be candidates for spin qubits with a long spin lifetime.
The hydrogen resist lithography technique is capable of preparing atomic scale planar dopant devices. This is enabled by a large difference in chemical reactivity of the bare and hydrogen passivated Si (001): 2x1 surface. Using a scanning tunneling microscope (STM), the hydrogen layer of the H:Si (001) surface is locally desorbed with nanometer precision leaving behind exposed areas of reactive Si. When a gaseous dopant precursor such as phosphine or diborane is introduced, the hydrogen layer acts as a resist and the dopants stick only to the desorbed areas. Compared to conventional fabrication methods, hydrogen resist lithography enables degenerate delta-doping with sub-nanometer lateral resolution and highly abrupt doping profiles.
In the first part of my talk I’ll present results on how an STM fabricated 6 x 6 nm n-type quantum dot in the Coulomb blockade regime can be used to characterize nanoscale barriers between dopant contacts [1]. We have since extended the hydrogen-resist technique to p-type doping with diborane and I’ll show initial electrical transport measurements on p-type dopant wires and a simple planar pn-junction fabricated by STM patterning. In addition, I’ll also outline our efforts to simplify the slow STM-based device fabrication with UHV-compatible pre-patterned SOI chips that do not require in-situ surface preparation and can be reintegrated into a CMOS process flow.
In a second part I’ll give an outlook on how dopants and field effect transistors can also be used as qubits and I’ll discuss ideas on how we would like to integrate such silicon based qubits with superconducting qubit technology.

On Thursday, 03.05.18, 1:30 pm 

  Dr. Amol Choudhary
ARC DECRA Fellow in the School of Physics University of Sydney

is holding a presentation on the topic:

"Miniature femtosecond laser sources"


Abstract:


The first ever laser consisted of a flash-lamp-pumped ruby rod and was built by T.H. Maiman in 1960 and since then lasers have captured the imagination of many physicists and the general public alike. Lasers can operate in the continuous wave (CW) regime, where the intensity remains constant as a function of time or in the pulsed regime where periodic pulses of light are emitted with durations in the order of femtoseconds (mode-locking) to nanoseconds (Q-switching).

There has been a recent focus on the development of pulsed laser sources with high (> 1 GHz) repetition rates owing to various applications such as non-linear microscopy, optical sampling, optical frequency comb metrology, and in the calibration of astronomical spectrographs (astro-combs). For most of these applications, the available sources are quite bulky, making the setup quite complicated, expensive and prone to instability. There is in general, a need for low-cost, multi-GHz sources which are compact, mass-producible and energy-efficient.
In this talk, I will give a brief overview of the state of the art high-repetition-rate, mode-locked lasers. I will then focus on my research on the development compact lasers based on waveguides, micron-scale structures that can efficiently guide light. I will also outline the importance of material platforms, especially crystals in the realization of such high-performance integrated devices.

April 27th and 28th 2017: Kick-off and laser materials meeting (ZLM)

briefkopf zlm blau


kick-off and laser materials meeting

on the occasion of the founding of the Zentrum für Lasermaterialien (ZLM)


taking place on
April 27th and 28th 2017
at the Leibniz-Institut für Kristallzüchtung (IKZ) in Berlin.


Workshop Schedule (Further details and updates regarding the program you find here)

Zentrum für Lasermaterialien / Center for Laser Materials (web presence)

 

 

As of March 1st 2017 Dr. Christian Kränkel will head the new Zentrum für Lasermaterialien - Kristalle (Center for Laser Materials - Crystals, ZLM-K) located at the Leibniz-Institut für Kristallzüchtung (IKZ).

The initiating project funded by the BMBF (project supervised by VDI) will be in close collaboration with the Ferdinand-Braun-Institut für Höchstfrequenztechnik (FBH) in Berlin, where the Zentrum für Lasermaterialien - Halbleiter (Center for Laser Materials - Semiconductors, ZLM-H) will be installed.

The ZLM-K will be equipped to characterize and qualify laser crystals and other optical materials with respect to laser applications. Besides research on new materials, another important aspect of the ZLM will be the supply and qualification of optical materials as a service job for research groups and industrial users.

To promote the ZLM in the community and to solicit input for future activities of the ZLM, we will hold a two-day ZLM kick-off and laser materials meeting at the IKZ in Berlin on April 27th and 28th.

During this meeting we will introduce the ZLM and demonstrate its abilities. Renowned experts from research and industry will provide lectures on the state-of-the art of German laser research. Also, lab-tours are offered at the IKZ and the FBH and there will be enough time to discuss and exchange with the other participants.

Participating in the workshop is free, but we would request an informal registration via e-mail to This email address is being protected from spambots. You need JavaScript enabled to view it. before April 3rd.

 

7th April 2017, 1pm: Colloquium - Dr. J. Janicsko - 'GERDA Phase II, from the concept to first results

 

on Friday April 7th 2017

Dr. Joseph Janicsko
TU München E15, Chair for Experimental Physics and Astroparticle Physics

is holding a presentation on the topic:

       "GERDA Phase II - from the concept to the first results"      

 


Abstract

The GERmanium Detector Array (GERDA) experiment, located at the Gran Sasso underground laboratory in Italy, is built for the search of neutrinoless double beta decay in Ge-76. GERDA operates bare high purity germanium detectors submersed in liquid Argon (LAr).
Phase I of the experiment was successfully completed reaching an exposure of about 21 kg yr with the best background level in the field (if normalized to region of interest) of 10exp-2 counts/ (keV kg yr). GERDA Phase I set a limit on the neutrinoless doublel beta decay of Ge-76 of 2.1 x 10exp25 yr.

In Phase II of the experiment 35.6 kg of enriched germanium detectors are operated. The application of active background rejection methods, such as a liquid argon scintillation light read-out and pulse shape discrimination of germanium detector signals, allowed to reduce the background index to the intended level of 10exp-3 counts/(keV kg yr).

I will report about the hardware upgrades that were done for Phase II, the production of 30 new Germanium detectors and the installation of the LAr veto. Finally, I will give the results of the first five month of Phase II data taking with 10.8 kg yr of exposure.

About the Meeting

Gallium oxide (Ga2O3) semiconductor electronics is emerging due to the material’s advantageous properties such as high band-gap and controllable doping from semi-insulating to conductive behavior. Ga2O3-based devices (field effect transistors, Schottky barrier diodes, photodetectors) with very promising properties have been demonstrated recently. However, the materials related technology is very challenging and there are a number of open issues in regard to a technology transfer to industry.

This meeting seeks to bring together leading scientists from industry and academia to discuss the challenges as well as the perspectives of Ga2O3-based electronics from a materials technology point of view and to build up a dedicated community. The topics span from bulk crystal, substrate, and epilayer preparation to structuring, device technology, and characterization.
The meeting is held in Berlin, Germany, in the context of the recently founded Leibniz ScienceCampus “Growth and fundamentals of oxides for electronic applications“ (GraFOx), with a strong participation of Japanese scientists, who are the leaders in this field.
The meeting is hosted by the Leibniz Institute for Crystal Growth (IKZ) Berlin. During the meeting, the IKZ will offer a lab tour, and there will be offered the possibility to visit neighboring institutes (FBH, ISAS, Humboldt University, PDI) on request.

About the Meeting

Oxides constitute the most versatile class of inorganic materials, and single crystals provide superior as well as homogeneous properties. Such crystals are used e.g. as optical, piezoelectric, or laser materials, and as substrates for piezoelectric and oxide electronic applications. As oxide crystals appear in many crystallographic structures and can be formed from nearly every element in the periodic table, the preparation of novel materials as well as the improvement of their structural quality is key for providing materials with improved or even novel characteristics. 

This workshop - under the auspices of the German Society of Crystal Growth (DGKK) - brings together scientists and scholars from industry, research labs, and universities to present and discuss the recent advances in the field of oxide crystals, dielectric materials, laser and non-linear optical crystals, solid-state lasers, and related topics. After taking place in the ISL in Saint-Louis (France) and the FEE in Idar-Oberstein (Germany), this 5th workshop 2016 is held in Berlin, Germany, at the Leibniz Institute for Crystal Growth (IKZ) for the first time. We are looking forward to welcoming you in Berlin! 

Meeting Details

  • Workshop Language is English

  • The workshop will start on Thursday, Sep 15, 2016, at 1 p.m., and end on Friday, Sep 16, 2016, around 1 p.m.

  • We plan for generous breaks between sessions for face-to-face discussions, and an IKZ lab tour after the event.

  • The attendance fee will be 40 Euro. An abstract book, hospitality during the workshop (coffee, snacks), as well as a dinner event on Thursday evening is included.

  • We recommend accommodating in the Adlershof/Köpenick area of Berlin. Lunch is offered at several restaurants around the campus.
