Space charge limited currents in liquid benzene

Abstract

AbstractThe current‐voltage characteristics of liquid benzene are interpreted by making use of the theory of space charge limited currents. Small deviations from theory can easily be explained by additional ion currents originating from impurities or self‐dissociation of benzene. It will be shown by several independent experiments that charge carrier injection, which is the basic assumption for the applicability of this theory, does in fact exist. Moreover, these experiments show that the charge carriers in question must be protons or defect electrons. Since their mobility has already been evaluated, the injection concentration of these carriers can be calculated from current‐voltage measurements.
