We have performed time-resolved measurements of the far-infrared photoresponse of two-dimensional electron systems in the quantum Hall regime. The photoresponse consists of two equally important components: the longitudinal component, caused by the photoinduced change of the longitudinal resistance R[sub xx], and the transversal component, caused by the photoinduced Hall currents and by the photoinduced change of R[sub xy]. Both these components are connected with two mechanisms of the photoresponse: a nonresonant bolometric, and a cyclotron-resonant contribution. [ABSTRACT FROM AUTHOR] |
