Abstract
Hole‐drift‐mobility measurements are presented for a molecularly dopedpolymer,p‐diethylaminobenzaldehyde‐diphenyl hydrazone in polycarbonate, over the widest temperature (213–373 K) and electric‐field range (3.3–111 V/μm) yet reported. Use of these data and graphical techniques which we introduce allow us to unambiguously determine for the first time the functional form of the electric field and temperature dependence of the mobility. Consistent with results obtained by others, the observed field dependence cannot be accounted for by any known hopping model. The observed temperature dependence suggests that the activation energy may be temperature dependent.This publication has 13 references indexed in Scilit:
