Abstract

We present measurements of the hole mobility in a photorefractive polymer composite as a function of temperature and applied electric field. The material is a composite, non-linear optical polymer bisphenol A 4-4'- nitroaminostilbene (bisA-NAS) mixed with 30 wt % of the hole transport agent diethylamino-benzaldehyde diphenyl hydrazone (DEH). The electric field and temperature dependencies of the hole mobility in the photorefractive polymer can be described at high fields by exp(βE 1/2 ) and exp [-(T 0/T) 2] respectively, in agreement with the disorder theory of the well-known hopping model developed for charge-transport in molecularly doped polymers. The mobilities at all temperatures decrease (β less than 0) with increasing fields up to a certain field, but increase again (β greater than 0) at higher fields.
