  • Nitride semiconductor light-emitting element
    Patent number: 9318645
    Abstract: A nitride semiconductor light-emitting element includes a second light-emitting layer, a third barrier layer, and a first light-emitting layer from a side close to a p-type nitride semiconductor layer. The first light-emitting layer includes a plurality of first quantum well layers and a first barrier layer provided between the plurality of first quantum well layers. The second light-emitting layer includes a plurality of second quantum well layers and a second barrier layer provided between the plurality of second quantum well layers. The second quantum well layers include a multiple quantum well light-emitting layer thicker than the first quantum well layers.
    Type: Grant
