Patent ID: 11335839

Abstract:
The object of the present invention is to provide a Group III nitride semiconductor light emitting diode having improved light extraction efficiency. A Group III nitride semiconductor light emitting diode according to the present disclosure includes an RAMO4 layer including a single crystal represented by the general formula RAMO4 (wherein R represents one or more trivalent elements selected from the group consisting of Sc, In, Y and lanthanoid elements, A represents one or more trivalent elements selected from the group consisting of Fe (III), Ga and Al, and M represents one or more divalent elements selected from the group consisting of Mg, Mn, Fe (II), Co, Cu, Zn and Cd); and a layered product stacked on the RAMO4 layer. The layered product includes at least a light emitting layer including a Group III nitride semiconductor. A degree of flatness of a surface, of the RAMO4 layer, opposite to the layered product is lower than a degree of flatness of a surface, of the RAMO4 layer, adjacent to the layered product.
