Abstract:
1. A semiconductor light-emitting device comprising: a substrate having a C-surface; an n-type semiconductor layer provided on the C-surface and including a nitride semiconductor; a p-type semiconductor layer including a nitride semiconductor; a light-emitting portion provided between the n-type semiconductor layer and the p-type semiconductor layer and including: a stacked body provided between the light-emitting portion and the n-type semiconductor layer and including: an average In composition ratio of the stacked body being higher than 0.4 times and not higher than 0.7 times an average In composition ratio of the light-emitting portion, assuming that the average In composition ratio of the light-emitting portion is (w×t the layer thickness t a thickness of the stacked body being equal to or greater than a thickness of the light-emitting portion, a thickness of the first layer being thicker than 1 nanometer and thinner than 3nanometers, a thickness of the second layer being thicker than 0 nanometer and thinner than 2 nanometers.
