Abstract:
A structure of a light emitting diode (LED), comprising:a substrate having a first surface on one side and a second surface on the other side, wherein a first electrode has been formed on said first surface; an epitaxial structure forming on said second surface, wherein said epitaxial structure is formed by a plurality of III-V compound semiconductor epitaxial layers including an active layer and a brag reflector layer sandwiched between said active layer and said substrate, and said Bragg reflector layer comprises: at least one oxidizble layer, wherein a portion of said at least one oxidizable layer is oxidized, thereby forming a current insulating layer; and at least one semiconductor layer, wherein said at least one semiconductor layer and said at least one oxidizable layer are stacked on each other wherein said oxidizable layer is easier to oxidize than said semiconductor layer; and a second electrode formed on said epitaxial structure.
