Microwave photoconductivity of a periodically modulated two-dimensional electron system: Striped states and overlapping Landau levels

Abstract

We study the dc-response of the striped state under microwave irradiation. The striped state can be modeled by a two-dimensional electron system under the influence of a unidirectional periodic modulation potential, which was examined in [J. Dietel et al. Phys. Rev. B (71), 045329 (2005)]. We further extend our study of the periodically modulated system to the case of strongly overlapping Landau levels and calculate the dark and photoconductivities. The strength of the modulation potential serves as an additional parameter which allows to vary the overlap of the Landau levels independently of the filling fraction.
