Method of growing non-polar a-plane gallium nitride

摘要

The invention provides a method of growing a non-polar a-plane gallium nitride. In the method, first, an r-plane substrate is prepared. Then, a low-temperature nitride-based nucleation layer is deposited on the substrate. Finally, the non-polar a-plane gallium nitride is grown on the nucleation layer. In growing the non-polar a-plane gallium nitride, a gallium source is supplied at a flow rate of about 190 to 390 mumol/min and the flow rate of a nitrogen source is set to produce a V/III ratio of about 770 to 2310.
