Diffusion and Drift of Charge Carriers in Molecularly Doped Polymers

Charge carrier transport in polyimides based on 9,10-bis(p-aminophenyl)anthracene

“…21 In summary, for amorphous Ðlms of soluble API-5, both hole and electron drift mobilities were found to be higher than those for other API Ðlms. This may be attributed to the absence of microcavities and other similar defects which form in the process of thermal imidization of insoluble APIs.…”

Non-Equilibrium Charge Transport in Disordered Organic Films

“…The theory applies to the case of moderate electric field and field dependence of mobility is not considered here. Hirao et al, 1995; attempt to interpret experimental data on the field dependence of carrier mobility under weak field, based on the assumption that the transport is quasiequilibrium at all times. Simple analytic expression for   Effects of anomalous field-assisted dispersion on initial TrEL kinetics cannot be ignored, basing on arguments following from both theoretical and experimental data.…”

Charge carrier transport in molecularly doped polycarbonate as a test case for the dipolar glass model

“…Yet the shape of the transients differs significantly from the result of the simple diffusive approximation, which was suggested for the description of experimental TOF transients. [59][60][61] Two major differences are the universality of the transients with respect to L and power law decay of the tail. It is worth noting that universality with respect to L naturally arises in the model where charge transport is described by the broad distribution of the effective carrier velocities, 51,62 but universality with respect to E cannot be explained by this approach.…”
