Abstract: The effect of electrode materials on the V-I characteristics of evaporated film of copper phthalooyanine (PcCu) has been studied. The electrode materials used were Au, Ag, Cu, Al and SnO₂, In₂O₃. If the top and bottom electrodes are made of the same metal-Au, Ag, Ou, the dark currents are symmetric with respect to the change of polarity of the applied voltage to the electrodes, and the V-I characteristics are typical of the SOLO type. The system Al/PoOu/Al showed blocking contact, presumably due to the oxide layer present on the evaporated Al electrode. In the case of Al as the top electrode and SnO₂ or In₂O₃ layer on a glass substrate as the bottom electrode, SOLC was observed when Al was biased negative. However, when SnO₂ was biased negative, electrode limited current behavior was observed. When In₂O₃ was biased negative, a negative resistance effect was observed.
