Abstract:
1. A light-emitting diode (LED), comprising: a p-n junction formed at a junction between a p-type GaN layer and an n-type GaN layer, wherein the n-type GaN layer is formed between a substrate and the p-type GaN layer; a first metal electrode layer provided on the p-type GaN layer, the first metal electrode layer configured to reflect light emitted by the p-n junction towards a light-emitting side of the LED; a first attachment layer interposed between and configured to electrically connect the p-type GaN layer and the first metal electrode layer, wherein the attachment layer comprises a transition metal oxide and is configured to transmit light emitted by the p-n junction and to transmit light reflected by the first metal electrode layer; a second metal electrode layer electrically contacting the n-type GaN layer on the same side of the p-n junction as a side of the p-n junction on which the first metal electrode layer contacts the p-type GaN layer, and a second attachment layer interposed between and in contact with the second metal electrode layer and the n-type GaN layer.
