Abstract:
1. A nitride semiconductor device comprised of one or more non-polar (Al, B, In, Ga)N layers grown on non-polar GaN, wherein the nitride semiconductor device is created using a process comprising: (a) growing one or more non-polar (Al, B, In, Ga)N layers on non-polar GaN, wherein the grown non-polar (Al, B, In, Ga)N layers comprise at least one light emitting quantum well structure including alternating layers of different bandgap such that wells are formed in the light emitting quantum well structure's energy profile, wherein the alternating layers of different bandgap include at least a quantum barrier layer and at least a quantum well layer, the quantum well layer has a thickness that is more than 5 nm and 11 nm or less, and the light emitting quantum well structure's peak photoluminescence (PL) emission wavelength and intensity are greater than PL emission wavelength and intensity from a light emitting non-polar (Al, B, In, Ga)N quantum well structure having a quantum well layer with a thickness less than 5 nm.
