Abstract
A nitride-based semiconductor light-emitting deviceincludes a GaN substrate, of which the principal surface is an m-plane, a semiconductor multilayer structurethat has been formed on the m-planeof the GaN-based substrate, and an electrodearranged on the semiconductor multilayer structure. The electrodeincludes an Mg alloy layerwhich is formed of Mg and a metal selected from a group consisting of Pt, Mo, and Pd. The Mg alloy layeris in contact with a surface of a p-type semiconductor region of the semiconductor multilayer structure
