Paper Abstract

Recent extensions of the standard Gaussian disorder model are discussed on the basis of Monte Carlo simulations. It is shown that spatial correlation of energetic disorder has a profound effect on the field-dependent mobility. This correlation could be responsible for the frequently observed Poole-Frenkel like behavior. It is also demonstrated that energetic and geometric disorder can act synergetically on hopping motion at high fields. Contrary to the usual assumption, geometric disorder can significantly affect the activation energy of high-field transport.
