Radiation Induced Oscillations of the Hall Resistivity in Two-dimensional Electron Systems

Abstract

We consider the effect of microwave radiation on the dissipative and Hall components of the conductivity and resistivity tensors in two-dimension electron systems. It is shown that photon-assisted impurity scattering of electrons can result in oscillatory dependences of both dissipative and Hall components of the conductivity and resistivity tensors on the ratio of radiation frequency to cyclotron frequency. The Hall conductivity and resistivity can include a component induced by microwave radiation which is an even function of the magnetic field. The phase of the dissipative resistivity oscillations and the polarization dependence of their amplitude are compared with those of the Hall resistivity oscillations. The developed model can clarify the results of recent experimental observations of the radiation induced Hall effect.
