✦ Synopsis

Abstract

Two problems are considered of the theory of two‐dimensional disordered semiconductors. The first one is that of a temperature dependence of the static conductivity when the Fermi level lies in the weak localization region. The second one concerns the frequency dependence of the light absorption coefficient due to electron transitions between the strongly (exponentially) and weakly localized states. It is shown that the latter experiments might reveal the form of the density of states in a weakly localization region.
