Abstract

The dark ac conductivity of α-NiPc films was measured as a function of frequency and temperature in sandwich structure devices employing symmetric gold ohmic contacts. Doping of NiPc films with oxygen was found to have a profound effect on its ac conductivity. It was concluded that at low temperatures a hopping-type process was the dominant conduction mechanism.
