    摘要: A nitride semiconductor device includes an active layer including a first nitride semiconductor layer and a second nitride semiconductor layer which are periodically stacked, the second nitride semiconductor layer having a different composition from a composition of the first nitride semiconductor layer. An energy at a lower edge of a conduction band in the first nitride semiconductor layer is lower than an energy at a lower edge of a conduction band in the second nitride semiconductor layer, and an energy at an upper edge of a valence band in the first nitride semiconductor layer is lower than an energy at an upper edge of a valence band in the second nitride semiconductor layer.

    摘要: A projection/recess structure is formed on a base substrate, and a layered structure of a nitride semiconductor laser is formed on the projection/recess structure. InGaN used for an active layer has an In intake efficiency and a growth rate that greatly vary with the plane direction. By use of this characteristic, an active layer structure low in In content and small in well layer thickness can be formed at a light-outgoing end facet by one-time crystal growth, and thus the transition wavelength of the active layer near the light-outgoing end facet can be shortened. As a result, since optical damage due to light absorption at the light-outgoing end facet can be greatly reduced, a nitride semiconductor laser capable of performing high light-output operation can be implemented.

    摘要: A nitride semiconductor light-emitting device includes a substrate (101) made of silicon, a mask film (102) made of silicon oxide, formed on a principal surface of the substrate (101), and having at least one opening (102a), a seed layer (104) made of GaN selectively formed on the substrate (101) in the opening (102a), an LEG layer (105) formed on a side surface of the seed layer (104), and an n-type GaN layer (106), an active layer (107), and a p-type GaN layer (108) which are formed on the LEG layer (105). The LEG layer (105) is formed by crystal growth using an organic nitrogen material as a nitrogen source.
