The dramatic progress of microelectronic and photovoltaic devices
would have been impossible without sophisticated techniques to detect
properties of dopants and defects. Highly sensitive spectroscopic
techniques and demanding theoretical methods had to be developed to
unravel the nature of these imperfections of the ideal crystalline
structure.
In a series of 5 lectures the fundamental properties of dopants and
defects are briefly discussed, and an outline is presented on recent
developments in defect identification and characterization. Several
representative examples will be presented from different semiconductors.

Prof. Jürg Weber is Chair of Semiconductor Physics at TU Dresden
since December 1999. He is engaged in the study of impurities and
defects in various semiconductors. His present area of specialization is
the study of hydrogen in various hosts and its importance in device
technology.
Prof. Jürg Weber was dean and vice rector, coeditor of several special
issues of "Applied Physics", and chaired and co-chaired several meeting
symposia. Since 1984 he organizes the annual workshop on "Point Defects
in Semiconductors".
