Abstract

A light-emitting device, such as a light-emitting diode (LED), has a group III-nitride current spreading layer which is either doped with transition metal, or comprises alternating transition metal nitride layer and group III-nitride layer. Also provided is a light-emitting device, such as a light-emitting diode (LED), having a quantum well doped with transition metal. Also provided is a method of forming transition-metal containing AlInGaN electrical conductive material.
