WebCharge transport below the mobility edge, where the charge carriers are hopping between localized electronic states, is the dominant charge transport mechanism in a wide range of disordered materials. This type of incoherent charge transport is fundamentally di erent from the coherent charge transport in ordered crystalline materials. WebCharge transport in nonordered semiconductors, such as polymers, is usually defined as flying of charges by thermal activation along the distribution of localized states or shallow …
