The Mott-CFO model for transport in amorphous semiconductors has a exact basis in the absence of electron-electron and electron-phonon interactions. Nevertheless, there are major discrepancies between the predictions of this "exact" theory and experimental observations. These difficulties can be completely eliminated by utilizing recent advances in our understanding of the density of states and of the energy- and temperature-dependent tail introduced into the mobility gap by the electron-phonon interaction.
