摘要:
Disclosed is a near UV light emitting device. The light emitting device includes an n-type contact layer, a p-type contact layer, an active area of a multi-quantum well structure disposed between the n-type contact layer and the p-type contact layer, and at least one electron control layer disposed between the n-type contact layer and the active area. Each of the n-type contact layer and the p-type contact layer includes an AlInGaN or AlGaN layer, and the electron control layer is formed of AlInGaN or AlGaN. In addition, the electron control layer contains a larger amount of Al than adjacent layers to obstruct flow of electrons moving into the active area. Accordingly, electron mobility is deteriorated, thereby improving recombination rate of electrons and holes in the active area.
