Abstract

Project A01 will explore the experimental design of materials providing access to helical topologically protected surface states and to spin-orbitronic effects in semiconductors, as well as their peculiar signatures in electronic magnetotransport. The project is structured into two parts: Part A concentrates on the three-dimensional topological insulator family (Bi1-xSbx)2(Te1-ySey)3, part B on two-dimensional electron systems in high spin-orbit indium arsenide-based thin films. Both project parts share a focus on custom-tailored band structure engineering, using multilayer heterostructures produced in molecular beam epitaxy, and on their magnetotransport properties.
