Terahertz Photovoltaic Detection of Cyclotron Resonance in the Regime of Radiation-Induced Magnetoresistance Oscillations

Abstract

We examine and compare the diagonal magnetoresistance, Rxx , and the photovoltage induced by microwave (42 <= f < 300 GHz) and terahertz (f >= 300 GHz) photoexcitation in the high mobility quasi-two-dimensional GaAs/AlGaAs system. The data demonstrate strong radiation-induced magnetoresistance oscillations in Rxx to 360 GHz. In addition, cyclotron resonance is observed in the photovoltage to 725 GHz. These results show that our high-mobility GaAs/AlGaAs two-dimensional electron system (2DES) specimens remain photoactive in magnetotransport into the terahertz band.
