Photon-Induced Vanishing of Magnetoconductance in 2D Electrons on Liquid Helium
Abstract
We report on a novel transport phenomenon realized by optical pumping in surface state electrons on helium subjected to perpendicular magnetic fields. The electron dynamics is governed by the photon-induced excitation and scattering-mediated transitions between electric subbands. In a range of magnetic fields, we observe vanishing longitudinal conductivity σxx→0. Our result suggests the existence of radiation-induced zero-resistance states in the nondegenerate 2D electron system.
