A transverse current rectification in graphene superlattice

A model for energy spectrum of superlattice on the base of graphene placed on the striped dielectric substrate is proposed. A direct current component which appears in that structure perpendicularly to pulling electric field under the influence of elliptically polarized electromagnetic wave was derived. A transverse current density dependence on pulling field magnitude and on magnitude of component of elliptically polarized wave directed along the axis of a superlattice is analyzed.Comment: 12 pages, 6 figure

Effect of Laser Radiation on the Energy Spectrum of 2D Electrons with Rashba Interaction

Abstract Quasienergy spectrum of the 2D electron gas with Rashba interaction under the influence of high-frequency electromagnetic wave polarized elliptically was obtained. Splitting of energy subbands in the material at the presence of high-frequency laser radiation was revealed. Magnetoconductivity as function of wave intensity was calculated. Conductivity of 2D electron gas was shown to have minimum at the certain values of amplitude of high-frequency electric field
