    摘要： In one embodiment, a method is disclosed for manufacturing a semiconductor light emitting device. The device includes a crystal layer including a nitride semiconductor. The crystal layer contains In and Ga atoms. The method can include forming the crystal layer by supplying a source gas including a first molecule including Ga atoms and a second molecule including In atoms onto a base body. The crystal layer has a ratio xs of a number of the In atoms to a total of the In atoms and the Ga atoms being not less than 0.2 and not more than 0.4. A vapor phase supply ratio xv of In is a ratio of a second partial pressure to a total of first and second partial pressures. The first and second partial pressures are pressure of the first and second molecules and degradation species of the first and second molecules on the source gas, respectively. (1−1/xv)/(1−1/xs) is less than 0.1.

    摘要： According to one embodiment, a semiconductor light emitting device includes an n-type semiconductor layer, a p-type semiconductor layer and a light emitting part. The light emitting part is provided between the n-type semiconductor layer and the p-type semiconductor layer and includes a first light emitting layer. The first light emitting layer includes a first barrier layer, a first well layer, a first n-side intermediate layer and a first p-side intermediate layer. The barrier layer, the well layer, the n-side layer and the p-side intermediate layer include a nitride semiconductor. An In composition ratio in the n-side layer decreases along a first direction from the n-type layer toward the p-type layer. An In composition ratio in the p-side layer decreases along the first direction. An average change rate of the In ratio in the p-side layer is lower than an average change rate of the In ratio in the n-side layer.
