【 摘 要 】

PN junction is the basic building block for the fabrication of optoelectronic devices. ZnO shows the n-type behaviour.P-type doping with suitable hole concentration and reduced defects is one of the major challenges in the fabrication of ZnO based devices. Nitrogen, Phosphorus, Arsenic and Bismuth are some of the potential p-type dopants, but none of them have desired electrical properties to fabricate p-n junction from ZnO. In the present work, we proposed a hybrid n-ZnO/p-GaN hetero-structure, in which n-type ZnO film is placed on Mg doped GaN film. Simulation results revealed that the electroluminescence intensities increases in hybrid LED structure and there is a strong sensitivity towards the layer properties in hybrid structure.
