Дисперсионный транспорт в молекулярно допированных полимерах: теория и эксперимент
Theoretical and experimental studies of the carrier transport in molecularly doped polymers (MDPs) have been reported. Theoretical analysis uses the multiple trapping (MT) model with an exponential and Gaussian trap distributions. Experimental technique is based on an electron gun technology enabling one to conduct time of flight measurements using the surface and the bulk carrier generation. The list of MDPs tested includes both polar and non_polar systems, some with varying dopant oncentration. Experimental results are compared to the MT model predictions as well as the mainstream theories of the hopping conduction in MDPs.
