摘要：

Electronic conduction studies-have been carried out on evaporated tin- and silicon-phthalocyanine thin films. The samples showed carrier excitation via a field-lowering mechanism with a logJ alpha V-1/2 2 plot and the current density-voltage (J-V) characteristics were studied. Both polarities showed two characteristic regions in the J-V plots at low and high voltages respectively leading to the conclusion that electrical conduction proceeds via Schottky and Poole-Frenkel emission.
