Abstract

We report on measurements of the conductivity as a function of electric field and temperature in strongly-localized In2O3-x films. At low temperatures and sufficiently intense fields, the conductivity is found to be temperature independent and the current-voltage characteristics follow the form suggested by Shklovskii in three as well as in two-dimensional samples.
