  • LIGHT-EMITTING DEVICE INCLUDING NITRIDE-BASED SEMICONDUCTOR OMNIDIRECTIONAL REFLECTOR
    Publication number: 20130248911
    Abstract: A light-emitting device includes a nitride-based semiconductor reflector. The light-emitting device includes a nitride-based reflector and a light-emitting unit that is disposed on the nitride-based reflector. The nitride-based reflector includes undoped nitride semiconductor layers and heavily-doped nitride semiconductor layers that are alternately stacked. The heavily doped nitride semiconductor layers are etched at their edges to form air layers between adjacent undoped nitride semiconductor layers.
