Abstract:
A nitride light emitting diode includes a substrate and a nitride buffer layer, an n-type layer, a quantum well light emitting layer, and a p-type layer over the substrate. The n-type layer is a superlattice structure formed by alternating undoped AlGaN layers and n-type doped GaN layers. The Al component of the undoped AlGaN layer is controlled to produce first stress that offsets the second stress produced by the n-type doped GaN layer, reducing crystal defects and wrapping caused by impurity doping of the n-type layer. Growth temperature and pressure of the n-type layer are controlled such that thickness of the n-type doped GaN layer is greater than that of the undoped AlGaN layer to improve surface roughness of the undoped AlGaN layer and form an n-type doped GaN layer with a flat surface. Series resistance, crystal defects and wrapping, and optoelectronic properties of the device are therefore improved.

Claim (Index 19):
The system of  claim 15 , wherein a thickness ratio of the undoped AlGaN layer and the n-type doped GaN layer is 1:2-1:4.
