Abstract:
1. A nitride-based semiconductor light-emitting device comprising: an n-type nitride-based semiconductor layer; an active layer formed on the n-type nitride-based semiconductor layer; a p-type nitride-based semiconductor layer formed on the active layer; an ohmic contact layer comprising a p-type nitride-based semiconductor covering a portion of an upper surface of the p-type nitride-based semiconductor layer on the p-type nitride-based semiconductor layer, wherein the ohmic contact layer has a thickness of about 100 to 200 nm and covers about 16 to 82% of the upper surface of the p-type nitride-based semiconductor layer; and a p electrode formed on the ohmic contact layer, the p electrode including a first portion contacting the p-type nitride-based semiconductor layer and a second portion contacting the ohmic contact layer.
