Trap-controlled and hopping modes of transport and recombination: similarities and differences

Analytic models are considered for trap-controlled and hopping carrier transport and recombination in disordered materials for both equilibrium and non-equilibrium (dispersive) regimes. It is shown that practically all characteristics of trap-controlled and hopping transport and recombination are similar at sufficiently high temperatures and for sufficiently long times. Experimental conditions which allow one to distinguish between different modes of carrier transport and recombination for a particular material are discussed.
