Monte Carlo simulation of thermally stimulated relaxation kinetics of carrier trapping in microcrystalline and two-dimensional solids

Abstract

Monte Carlo calculations have been performed in order to study the kinetics of carrier trapping in sparsely populated systems. The method of calculation overcomes the problem of a ‘very large number’ of carriers participating simultaneously in the relaxation process. The algorithm of the simulation is described. The calculations were performed for the case of a linearly varying temperature. Possible consequences for thermally stimulated conductivity and thermoluminescence performed on microcrystalline or two-dimensional solids are discussed.
