Abstract
The low-field electric conduction in amorphous chalcogenides is here investigated by means of a Monte Carlo implementation of a full three-dimensional variable-range hopping transport model between localized states. Macroscopic features of the electrical conduction are obtained from numerical simulations and then used toestimate the linear region of the current density-voltage. The latter fits the experimentaldata. Our transport scheme also reproduces the temperature behavior of the conductivity typical of non-crystalline solids. The present investigation provides a basic schemeto be extended for the analysis of electron transport in chalcogenide glasses at high-field regimes.
