Hole mobilities in a hydrazone-doped polycarbonate and poly(styrene)
Abstract
The hole mobilities in p-diethylaminobenzaldehyde diphenylhydrazone-doped polycarbonate and poly(styrene) have been measured. These data have been deconvoluted to determine the effect of the host polymer on the transport parameters. The results are compared to the predictions of the disorder formalism of Bässler and co-workers and the polaron model. It is found that the electric field dependence of the mobility, the activation energy, the width of the hopping site manifold, and the positional disorder parameter are all independent of the polymer host; only the exponential tail of the electronic wavefunction depends on the host polymer. © 1993.
