Abstract

A semiconductor light-emitting element comprising a monocrystal substrate; a buffer layer formed directly on the monocrystal substrate and comprising a monocrystal Al.sub.x Ga.sub.1-x N layer (0<x<1); and element-forming layer formed on the buffer layer and comprising Al.sub.x Ga.sub.y In.sub.1-x-y N (0.ltoreq.x+Y.ltoreq.1, 0.ltoreq.x, Y.ltoreq.1). The half-value width of an X-ray rocking curve of the buffer layer should preferably be 5 minutes or less, more preferably 90 seconds or less.
