Abstract

See full text

According to one embodiment, a semiconductor light emitting device includes a first semiconductor layer of a first conductivity type, a second semiconductor layer of a second conductivity type and a light emitting layer provided between the first semiconductor layer and the second semiconductor layer. The device also includes a first electrode layer having electrical continuity with the first semiconductor layer and a second electrode layer provided on the second semiconductor layer, the second electrode layer including a metal portion having a thickness not less than 10 nanometers and not more than 100 nanometers along a direction from the first semiconductor layer to the second semiconductor layer. A plurality of apertures penetrates the metal portion along the direction, each of the apertures viewed along the direction having equivalent circle diameters of not less than 10 nanometers and not more than 5 micrometers, and a Schottky barrier is provided between the second semiconductor layer and the metal portion.
