Correlation effects in the impurity-limited mobility of quantum wires

Abstract

We study many-body effects, introduced via the local-field corrections, on the mobility of quasi-one-dimensional electron systems. The low-temperature mobility due to remote-impurity doping, homogeneous-background doping, interface roughness, and alloy-disorder scattering is calculated using the relaxation time approximation. We find that correlation effects significantly reduce the mobility at low density. © 1995 The American Physical Society.
