Abstract
An organic semiconductor have been discovered for various applications such as in organic light-emitting diodes (OLEDs). The metal oxides such as zinc oxide (ZnO) provide an interesting alternative for conventional low work function metals as electron injection layer in OLEDs. This study focuses the preparation of ZnO nanotetrapods at different evaporation temperature using thermal chemical vapor deposition (CVD). These will provide better performance and suitable for optoelectronic device.
