Robinson, John P. and Kennett, Malcolm P. and Cooper, Nigel R. and Falko, Vladimir I. (2004) Surface acoustic wave induced magnetoresistance oscillations in a 2D electron gas. Physical Review Letters, 93 (3). 036804. ISSN 1079-7114Full text not available from this repository.
We study the geometrical commensurability oscillations imposed on the resistivity of 2D electrons in a perpendicular magnetic field by a propagating surface acoustic wave (SAW). We show that, for ω<ωc, this effect contains an anisotropic dynamical classical contribution increasing the resistivity and a nonequilibrium quantum contribution isotropically decreasing the resistivity, and we predict zero-resistance states associated with geometrical commensurability at large SAW amplitude.
