Hole mobilities that decrease with increasing electric fields in a molecularly doped polymer

Abstract

The hole mobilities in the molecularly doped polymer, pyrazoline: polycarbonate, have been characterized as a function of the electric field, temperature, and pyrazoline concentration. At sufficiently low concentrations (10%) and high temperatures (T≫ 375K), the mobility decreases as the electric field increases, contrary to intuition but consistent with known empirical relations. © 1988.
