Transport phenomena in topological insulators (A03)

• Subject Area: Experimental Condensed Matter Physics
• Term: since 2015
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 258499086

This project focuses on two aspects: Transport properties of topological insulator materials based on HgTe and the necessary technology for the device fabrication. Two main goals are the lithographic development of reliable ohmic contacts, which sustain high magnetic fields and a split-gate technology. The feasibility of potential device applications such as a spin-controlled transistor will be explored.
