Descrizione Cyclotron resonance assisted photocurrents
This work is based on the master thesis of Matthias Lindner written in 2015 at the University of Regensburg at the working group of Prof. Dr. Ganichev. I report on the observation of cyclotron resonance induced photocurrents, excited by continuous wave terahertz radiation, in a 3D topological insulator (TI) based on an 80 nm strained HgTe film. The analysis of the photocurrent formation is supported by complimentary measurements of magneto-transport and radiation transmission. I demonstrate that the photocurrent is generated in the topologically protected surface states.
