Low energy spectroscopy of HgTe based magnetic and nonmagnetic topological insulators and semimetals (A07)

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

This project uses polarization resolved far-infrared magneto-optical spectroscopy to provide detailed knowledge of the energetic band-structure of HgTe based topological thin films. The main objective is to establish the region of parameter space, in which HgTe based thin films energetically constitute a 3D topological insulator or Weyl semimetal phase.
