Electron-electron scattering in linear transport in two-dimensional systems
Research output: Contribution to journal › Journal article › Research › peer-review
We describe a method for numerically incorporating electron-electron scattering in quantum wells for small deviations of the distribution function from equilibrium, within the framework of the Boltzmann equation. For a given temperature T and density n, a symmetric matrix needs to be evaluated only once, and henceforth it can be used to describe electron-electron scattering in any Boltzmann equation linear-response calculation for that particular T and n. Using this method, we calculate the distribution function and mobility for electrons in a quantum well, including full finite-temperature dynamic screening effects. We find that at some parameters that we investigated, electron-electron scattering reduces the mobility by approximately 40%.
