Zinc oxide nanorods as electron transport layer in MEH-PPV/ZnO Organic Light Emitting Diodes / Shafinaz Sobihana Shariffudin

This thesis discusses on the development of zinc oxide (ZnO) nanorods for the application as electron transport layer in MEH-PPV/ZnO Organic Light Emitting Diode (OLED). In general, the mobility of holes is higher than electrons in most semiconducting organic material. Therefore, it is essential to...
