摘要：

It is found that voltage-current characteristics of Al/C60 interfaces are fundamentally altered from a strong rectifying junction to an Ohmic junction where a LiF interlayer is used. Al/LiF/C60 has been used as an Ohmic cathode for organic light-emitting diode (OLED). The Ohmic cathode together with a high electron mobility of the fullerene layer have lead to a drastic reduction in the driving voltage and consequently a significant increase in the power efficiency of OLED.
