Abstract

Optical transmission spectrum and temperature dependence of the current–voltage characteristics of a plane-parallel rubrene wafer prepared by the vapor transport method have been investigated. The band gap is determined from the optical transmission spectrum. It is established that the current–voltage characteristics can be explained within the framework of the model of space-charge-limited currents. The current-flow processes are significantly affected by traps.
