An adiabatic model of trap-controlled dispersive transport and recombination

Abstract

A model of trap-controlled dispersive transport and recombination is presented. Carrier transport and recombination under non-equilibrium conditions are shown to have features characteristic of an adiabatic process with the time-dependent density of ‘deep’ localized states being a rate-limiting function. Hence the latter function governs time dependencies of dispersive transport and recombination. An adiabatic equation of trap-controlled dispersive transport and recombination is derived. The general results are applied to particular models of energetic distribution of localized states.
