Local photocurrent generation in thin films of the topological insulator Bi2Se3

C. Kastl, T. Guan, X. Y. He +3

We report on the optoelectronic properties of thin films of Bi2Se3 grown by molecular beam epitaxy. The films are patterned into circuits with typical extensions of tens of microns…

Enlarged magnetic focusing radius of photoinduced ballistic currents

Markus Stallhofer, Christoph Kastl, Marcel Brändlein +5

We exploit GaAs-based quantum point contacts as mesoscopic detectors to analyze the ballistic flow of photogenerated electrons in a two-dimensional electron gas at a perpendicular…
