发明名称 Semiconductor light emitting element and method for manufacturing the same
摘要 According to one embodiment, a semiconductor light emitting element includes a first semiconductor layer of an n-type, a second semiconductor layer of a p-type, and a light emitting unit. The first semiconductor layer includes a nitride semiconductor. The second semiconductor layer includes a nitride semiconductor. The light emitting unit is provided between the first semiconductor layer and the second semiconductor layer. The light emitting unit includes a plurality of well layers stacked alternately with a plurality of barrier layers. The well layers include a first p-side well layer most proximal to the second semiconductor layer, and a second p-side well layer second most proximal to the second semiconductor layer. A localization energy of excitons of the first p-side well layer is smaller than a localization energy of excitons of the second p-side well layer.
