Paper Abstract

The similarity of charge transport in a wide variety of molecularly doped polymers implies that the key unifying feature in these materials is their inherent disorder. Much attention has recently been focused on the role of permanent dipole moments of the dopants, and of the host polymer repeat unit. Theoretical considerations show that energy fluctuations arising from the interaction of a photoinjected charge with randomly placed dipole moments are approximately characterized by a Gaussian distribution, had have long- range spatial correlations. Furthermore, a theoretical link between correlated Gaussian site energies and the Poole- Frenkel has recently been established. This talk will provide an overview of recent progress in understanding transport in molecularly doped polymers in terms of a model of correlated Gaussian disorder.
