Acoustic phonon-limited resistivity in spin-orbit coupled 2DEG: Deformation potential and piezoelectric scattering

Abstract

We study the interaction between electron and acoustic phonon in a Rashba spin-orbit coupled two dimensional electron gas using Boltzmann transport theory. Both deformation potential and piezoelectric scattering mechanisms are considered in the Bloch-Gruneisen (BG) as well as in the equipartition (EP) regimes. Effect of the Rashba spin-orbit interaction on the temperature dependence of resistivity in the BG and EP regimes has been discussed. We find effective exponent of the temperature dependence of the resistivity in the BG regime decreases due to spin-orbit coupling.
