Abstract:
A nitride semiconductor light-emitting device comprising:a substrate; an n-type nitride semiconductor layer and a p-type nitride semiconductor layer formed on said substrate; and one or a plurality of well layers and one or a plurality of barrier layers of GaN provided between said n-type nitride semiconductor layer and said p-type nitride semiconductor layer, wherein said well layer is constituted of nitride semiconductor containing at least N and element X including at least one element selected from the group consisting of As, P and Sb, said nitride semiconductor of said well layer has at most 30% in atomic percent represented by expression {Nx/(NN+Nx)}Ã—100 where Nx represents the number of atoms of said element X and NN represents the number of atoms of said N, and said well layer has a thickness ranging from 0.4 nm to 4.8 nm.
