Abstract

We report on the observation of linear and circular magnetogyrotropic photogalvanic effects in InSb/(Al,In)Sb quantum well structures. We show that intraband (Drude-type) absorption of terahertz radiation in the heterostructures causes a dc electric current in the presence of an in-plane magnetic field. The photocurrent behavior upon variation of the magnetic field strength, temperature, and ...
