We have observed the quantum Hall e ect in a high mobility two-dimensional electron gas to ΓΏlling factors up to 80 at 0.3 K. This demonstrates the presence of both localized and extended states at low ΓΏeld, and explains the failure of the standard semi-classical analysis of Shubnikov-de Haas (SdH) o
## Abstract Two problems are considered of the theory of twoβdimensional 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 a
