Abstract
We theoretically study the electron-electron scattering rate tau(ee)(- 1) for electrons in a two-dimensional electron gas with a perpendicula r magnetic field, within the GW and plasmon-pole approximations, as fu nctions of temperature T, impurity scattering rate Gamma and magnetic field B. The r(ee)(-1) increases with increasing T and increasing Gamm a, and shows the structure of the Landau levels as B is changed. (C) 1 998 Academic Press Limited.
