Abstract:
1. A semiconductor light-emitting device comprising: an n-type semiconductor layer having a face equivalent to a 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 barrier layer including In a well layer stacked with the barrier layer, including In a stacked body provided between the light-emitting portion and the n-type semiconductor layer and including: a first layer including In a second layer stacked with the first layer, including In 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 3 nanometers, and a thickness of the second layer being thicker than 0 nanometer and thinner than 2 nanometers.
