Abstract

By use of Monte Carlo simulation techniques it has been shown that inclusion of random variations of the wavefunction overlap parameter ('off-diagonal' disorder) generates Poole-Frenkel behavior of the charge-carrier mobility (μ) in random organic solids within an experimentally relevant range. The results are in quantitative agreement with experimental data, notably the work of Peled and Schein (Chem. Phys. Lett., 153 (1988) 422) reporting on a temperature-induced change of sign of the field dependence of μ.
