Engineering electronic hybridization at the atomic scale

BildCopyright: Prof Dr. Krogstrup

Hybrid epitaxial materials has huge potential for the realization of new topologcial states of matter. The actual electronic hybridization depends on the detailed atomic structure which sets both the band structure, band aligment and quality of the materials. I will discuss the hybrid epitaxy of semiconductor/superconductor/magnetic heterostructures with the motivation to engineer low noise hybrid materials with energy bands that are aligned to realize wavefunctions with properties that maximize topological protection. 

We focus on crystal growth by MBE on different III-V semiconducting platforms and discuss the mechanisms of hybrid epitaxy that leads to materials with appropriate band alignments, a key requirement for engineering desired electronic hybridization.
