摘要： 本文研究了不同电极材料(Au、Ag、Cu、Al和SnO2、In2O3)对酞菁铜(PcCu)蒸发膜V-I特性的影响.用同样的金属(Au、Ag、Cu)作顶底电极时,改变电极极性所得暗电流是对称的,V-I特性属典型的SCLC型.而Al/PcCu/Al体系呈现阻挡接触,估计这是蒸得的Al电极上存在氧化层之故.当Al作顶电极,玻璃基片上的SnO2或In2O3层作底电极时,Al极加负电压观察到SCLC,而当SnO2极加负电压时观察到电极限制电流,In2O3极加负电压时观察到负阻效应.

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.
