我们对二维电子系统在量子霍尔区的远红外光响应进行了时间分辨测量。光响应由两个同样重要的分量组成：纵向分量由光致纵向电阻Rxx的变化引起，横向分量由光致霍尔电流和光致Rxx的光致变化引起。这两个部分都与光响应的两种机制有关：非共振测辐射热学和回旋共振贡献。
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 Rxx, and the transversal component, caused by the photoinduced Hall currents and by the photoinduced change of Rxy. Both these components are connected with two mechanisms of the photoresponse: a nonresonant bolometric, and a cyclotron-resonant contribution.
