The temperature dependence of the electronic structure of Si $delta$-doped GaAs

Abstract

We investigated theoretically the change of electronic properties of Si $delta$-doped GaAs layer as a function of temperature. We studied the influence of temperature on the donor concentration for a nonuniform distribution, which is taken as different from the known Gaussian distribution. In order to obtain the electronic structure we have calculated self-consistent Schrödinger - Poisson equations. We have seen that the change of the electronic properties as dependent on temperature is less pronounced at higher doping concentration.
