Abstract
The disclosed technology relates to a light-emitting diode (LED) and a method of fabricating the same. In one aspect, the LED includes a GaN p-n junction formed at a junction between a p-type GaN layer and an n-type GaN layer. The LED further includes a first metal electrode layer provided on the p-type GaN layer, where the first metal electrode layer is configured to reflect light emitted by the p-n junction towards a light emitting side of the LED. The LED additionally includes an attachment layer interposed between and configured to electrically connect the p-type GaN layer and the 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 metal electrode layer.
