Abstract
Devices having nitride quantum dots and methods of manufacturing the same are provided. The device includes a nitride group material substrate, a plurality of nanorods that are formed on the nitride group material layer and are separated from each other, and a nitride quantum dot on each of the nanorods. A pyramid-shaped layer may be further formed between each of the nanorods and the nitride quantum dot. The nanorods and the nitride quantum dot are covered by an upper contact layer. A plurality of nitride quantum dots may be formed on each of the nanorods and the respective nitride quantum dots may have different sizes.
Claims19
