Exchange-Correlation Effects in the Impurity-Limited Mobility of GaAs Quantum Wires

Authors: B. TANATAR

Abstract: We study the many-body effects described by the local-field corrections on the mobility of quasi-one dimensional electron systems. The low temperature mobility due to remote-impurity doping and interface-roughness scattering is calculated within the relaxation time approximation. We find that correlation effects significantly reduce the mobility at low density.
