Comparison of charge transport models in molecularly doped polymers
Abstract
It is well known that charge carrier mobilities p. in molecularly doped polymers, determined by transient photoconductivity experiments, depend on the temperature T, the mean distance p between dopant molecules and the electric field E. Recently introduced deconvolution procedures have made possible the systematic analysis of the dependence of p on T, p and E. Two theories which have been proposed to account for the data are the polaron theory and the disorder theory of Bassler and co-workers. The current status of these and other theories in explaining the data is reviewed. © 1992 Taylor & Francis Ltd.
