摘要： A semiconductor light emitting device includes a semiconductor light emitting structure including first and second conductivity type semiconductor layers, and an active layer disposed therebetween, first and second electrodes connected to the first and second conductivity type semiconductor layers, respectively, and a fine pattern for light extraction, formed on a light emitting surface from which light generated from the active layer is emitted. The fine pattern for light extraction is formed as a graded refractive index layer having a refractive index which decreases with vertical distance from the light emitting surface.

摘要： A nitride semiconductor light emitting device includes n-type and p-type nitride semiconductor layers, and an active layer disposed between the n-type and p-type nitride semiconductor layers and having a stack structure in which a plurality of quantum barrier layers and one or more quantum well layers are alternately stacked. A net polarization of the quantum barrier layer is smaller than or equal to a net polarization of the quantum well layer. A nitride semiconductor light emitting device can be provided, which can realize high efficiency even at high currents by minimizing the net polarization mismatch between the quantum barrier layer and the quantum well layer. Also, a high-efficiency nitride semiconductor light emitting device can be achieved by reducing the degree of energy-level bending of the quantum well layer.

摘要： A nitride semiconductor light emitting device includes n-type and p-type nitride semiconductor layers, an active layer disposed between the n-type and p-type nitride semiconductor layers and having a structure in which a plurality of quantum barrier layers and one or more quantum well layers are alternately stacked, and an electron blocking layer disposed between the active layer and the p-type nitride semiconductor layer. The electron blocking layer has greater bandgap energy than a quantum barrier layer adjacent to the electron blocking layer among the plurality of quantum barrier layers, and has a net polarization equal to or smaller than that of the quantum barrier layer adjacent thereto. The nitride semiconductor light emitting device can achieve high efficiency in every current region by minimizing a net polarization mismatch between a quantum barrier layer and an electron blocking layer.
