Effect of Electron-Electron Scattering on the Conductance of a Quantum Wire
Abstract
Electron-electron scattering conserves total momentum and does not dissipate momentum directly in a low-density system where the Umklapp process is forbidden. However, it can still affect the conductance through the energy relaxation of the electrons. We show here that this effect can be studied with arbitrary accuracy in a multi-sublevel one-dimensional single quantum wire system in the presence of roughness and phonon scattering using a formally exact solution of the Boltzmann transport equation. The intrasubband electron-electron scattering is found to yield no net effect on the transport of electrons in 1D with only one sublevel occupied. For a system with a multi-level occupation, however, we find a significant effect of inter-sublevel electron-electron scattering on the temperature and density dependence of the resistance at low temperatures.
