Подобие кривых переходного тока при дисперсионном транспорте: теория и эксперимент
The influence of an electric field on the shape of transient current curves for both surface and uniform generation was studied by numerically solving the multiple capture model equations with an exponential energy distribution of traps. At dispersion parameters not exceeding 0.5, the calculation results satisfactorily coincided with the analytic data. Similarity of time_of_flight curves and its violations related to the inclusion of the frequency factor and radiation pulse width were studied. The results of the theoretical analysis were used to interpret the experimental data obtained for two typical molecularly doped polymers. The question of the relation between the model under consideration and the Riemann–Liouville fractional derivative formalism is discussed.
