Abstract :
The surface potential kinetics for disordered materials described by Gaussian trap distributions was calculated on the basis of a stochastic hopping model. It is shown that an exact estimation of the transit time is possible only for narrow trap distributions. The transit time increases with the square of the standard deviation of the Gaussian trap distribution
