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 4):
The nitride light emitting diode of  claim 1 , wherein a thickness of the n-type doped GaN layer of the superlattice structure is greater than that of the undoped AlGaN layer, to thereby adjust surface flatness of the superlattice structure and improve crystal quality of the superlattice structure.
