Probing the Electrostatics of Integer Quantum Hall Edges with Momentum-Resolved Tunnel Spectroscopy
M. Huber, M. Grayson, D. Schuh +4
We present measurements of momentum-resolved magneto-tunneling from a perpendicular two-dimensional (2D) contact into integer quantum Hall (QH) edges at a sharp edge potential crea…

Spin-photocurrent in p-SiGe quantum wells under terahertz laser irradiation
V. V. Bel'kov, S. D. Ganichev, Petra Schneider +7
A detailed study of the circular photogalvanic effect (CPGE) in SiGe structures is presented. It is shown that the CPGE becomes possible due to the built-in asymmetry of quantum we…
