Abstract
In insulating, three-dimensional films of granular In2O3-x, the resistance behavior is well described by the Mott variable-range-hopping (VRH) expression, Rexp(TMott/T)1/4; this Mott VRH dependence of the resistance is observed in the liquid-helium to liquid-nitrogen temperature regime. In the same temperature interval, the Hall constant RH is observed to be independent of temperature. This result is in conflict with the theoretical prediction of Gruenewald et al., where an temperature dependence is anticipated.
