Topological matter (A04)

• Subject Area: Experimental Condensed Matter Physics ; Thermodynamics and Kinetics as well as Properties of Phases and Microstructure of Materials
• Term: since 2016
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 277146847

In this project we explore the new physics of topological insulators (TI), topological semimetals and topological superconductors (TSC) by synthesis of bulk crystals, thin films and also nanowires. Besides the semimetal ZrTe5 we grow low-disorder TI single crystals and TSC candidates. For thin films of magnetic Tis, we aim at confirming chiral Majorana edge states in a quantum anomalous Hall insulator. TI Nanowires are grown and fabricated to search for signatures of topological uperconductivity.
