Abstract:
1. A method for manufacturing a GaN based optical device, the method comprising the steps of: growing a p-type nitride semiconductor layer using NH doping the p-type nitride semiconductor layer with magnesium (Mg), wherein the p-type nitride semiconductor layer includes gallium and the molar flow ratio of hydrazine based source and gallium (Ga)(V(hydrazine based source) /III(gallium)) is in a range of 1 to 300; the p-type nitride semiconductor layer includes gallium and the molar flow ratio of NH the p-type nitride semiconductor layer is grown at a temperature of 700° C. to 1100° C. and at a pressure of 20 torr to 760 torr; the p-type nitride semiconductor layer has a thickness of 10 Å to 10000 Å; and the p-type nitride semiconductor layer exists on an active layer that generates light by recombining holes and electrons.
