Abstract:
A semiconductor light-emitting device having a multilayered structure formed by sequentially forming layers of Group III nitride semiconductors (Al.sub.x Ga.sub.1-x).sub.1-y In.sub.y N (0.ltoreq.y.ltoreq.1) which are different from each other in chemical composition ration, one upon another, on a substrate.wherein two adjacent layers within said multilayered structure, which include a lower layer having a lattice constant larger than a lattice of an upper layers of said two adjacent layers, have a portion close to an interface of said two adjacent layers doped such that an element different from said Group III nitride semiconductors is added to said portion at a concentration higher than that in other portions of said two adjacent layers.
