The continued development of functional quantum materials is a demanding task with high priority for material science and applied research. Among existing quantum materials, 2D-materials possess outstanding opportunities. Yet, the full potential of exploiting their functionalities is only revealed through novel heterostructures. It is exactly this goal of the strategic cooperation “layer transfer for 2D-heterostructures”.

In principle, layer transfer allows the combination of crystalline materials without thermodynamic, kinetic or geometric constraints (lattice mismatch, crystal symmetry, combination of different thermodynamic phases, (de-)wetting properties), limiting classical bulk crystal growth or thin film epitaxy. In this way, layer transfer could set a new paradigm in fabricating innovative crystalline heterostructures with tailor-made properties. Therefore, layer transfer has established itself as a new "bottom-up" method for the construction of novel "2D goes 3D" materials and represents a fundamentally new synthesis path of crystalline materials.

We see our strategic cooperation "Layer transfer for 2D heterolayers" as an integral part of the overarching efforts towards material sovereignty and we aim to make a significant contribution to the development of quantum materials in the Berlin area.
