摘要：

We present experimental results on current injection from different metal electrodes into copper-phthalocyanine (Cu-Pc). The current-voltage (J-V) characteristics and current injected at the contact are investigated as a function of Schottky energy barrier, thickness of organic semiconductor, and temperature. These results are interpreted using a consistent description of J-V characteristics through the injection limited current in the case of high Schottky energy barriers and space charge limited current in the case of low Schottky energy barrier.
