Радиационно-физические аспекты переноса носителей заряда в молекулярно допированном полистироле

Химия выскоих энергий . 2011. Т. 45. № 3. С. 233-240.

Hole transport in low-polarity polystyrene (PS) doped with 10 wt % tritolylamine was studied. The radiation induced mode of the time-of-flight technique (TOF) with the carrier generation zone of a variable thickness was used. A theoretical treatment of the data in terms of the Gaussian disorder model has shown the mobility value to be fundamentally inconsistent with the flat shape of the plateau, a contradiction that cannot be resolved within the framework of this model. It has been shown that hole transport is actually dispersive, rather than quasi-equilibrium. The contribution of radiation conductivity of the polymer matrix to the TOF signal was evaluated.
