Abstract

A compound semiconductor light-emitting device includes a cubic SiC substrate, and an Ga.sub.x Al.sub.y In.sub.1-x-y N (0.ltoreq.x.ltoreq.1, 0.ltoreq.y.ltoreq.1) layer formed on the (111) surface of the cubic-crystal SiC substrate. The surface of the Ga.sub.x Al.sub.y In.sub.1-x-y N layer, which opposes the substrate, is an N surface, and the light-emitting device has a pn junction.
