| Abstract | We calculate the electron elastic mean free path due to ionized impurity scattering in semiconductor quantum wires, using a scheme in which the screened ionized impurity potential and the electron screening self-consistently determine each other. By using a short-range scattering potential model, we obtain an exact solution of the self-energy within the self-consistent Born and “noncrossing” approximations. We find that, compared to the mean free path for the bare unscreened potential lbare, the calculated mean free path including self-consistent screening lsc is substantially larger, going as lsc ∼ lbare[ln(lbare)] 2 for large lbare.
