Abstract:
1. A manufacture method for a ZnO based light emitting device, comprising: (a) forming an n-type ZnO buffer layer on a Zn polarity plane of a substrate; (b) forming an n-type ZnO layer over said n-type ZnO buffer layer; (c) forming an n-type ZnMgO layer over said n-type ZnO layer; (d) forming a ZnO/ZnMgO quantum well layer over said n-type ZnMgO layer, said ZnO/ZnMgO quantum well layer being formed by alternately laminating a ZnO layer and a ZnMgO layer; (e) forming a p-type ZnMgO layer over said ZnO/ZnMgO quantum well layer; and (f) forming a p-type ZnO layer over said p-type ZnMgO layer, wherein said n-type ZnO layer is formed in a Zn rich condition in said step (b),
