Light-emitting diode for emitting ultraviolet light
An ultraviolet (UV) light-emitting diode including an n-type semiconductor layer, an active layer disposed on the n-type semiconductor layer, a p-type semiconductor layer disposed on the active layer and formed of p-type AlGaN, and a p-type graphene layer disposed on the p-type semiconductor layer and formed of graphene doped with a p-type dopant. The UV light-emitting diode has improved light emission efficiency by lowering contact resistance with the p-type semiconductor layer and maximizing UV transmittance.
