Abstract
The dark electrical conductivity σ of In-doped CdS films does not show a simply activated behavior. Appreciable curvature is seen in graphs of log σ vs T−1. This has been attributed to a temperature-dependent activation energy or to a tendency of σ towards saturation at low temperatures. We suggest that it arises because, as the doping is reduced, the data tend to follow log σ=constT rather than log σ=const T−1. This linear temperature dependence of log σ has also been seen for off-stoichiometric SiO2 films, among other low-conductivity solids, and we point out that it is a characteristic behavior which was anticipated more than 20 years ago in a model of quantum tunneling through a vibrating barrier.
