Abstract:
A nitride semiconductor light emitting device, comprising:a GaN substrate into which a group VII element is doped; an intermediate layer section provided on the GaN substrate; and a light emitting layer provided on the intermediate layer section, wherein the intermediate layer section has a sufficient thickness to prevent the group VII element diffused from the GaN substrate from being detected in the light emitting layer, wherein the intermediate layer section comprises a plurality of layers including an n-GaN base layer, an n-AlGaN cladding layer and an n-InGaN guide layer, which are arranged in this order from the GaN substrate side, wherein said intermediate layer includes a material selected from the group consisting of Si, Se, S, Sn, Te, Ge and Mg, and wherein the GaN substrate is in contact with an ohmic electrode.
