摘要：
We have investigated properties of organic light emitting diodes (OLEDs) with ZnO as a hole injection layer (HIL). It is found the optimum thickness of the ZnO HIL to be 0.5 nm. On fabrication of the OLED, it is confirmed that UV/ozone treatment after deposition of the ZnO layer is important. Lower operating voltage of the OLED with ZnO compared to those with other HILs seems to be caused by lower barrier height between HIL and hole transport layer (HTL).
