Abstract:
A nitride-based light-emitting device includes, on a GaN substrate: a first-conductivity-side first semiconductor layer; an active layer; and a second-conductivity-side first semiconductor layer, in the stated order, and further includes an electron barrier layer of a second conductivity type between the active layer and the second-conductivity-side first semiconductor layer, the electron barrier layer including a nitride-based semiconductor containing at least Al. The electron barrier layer has a first region in which an Al composition changes. The Al composition in the first region monotonically increases in a direction from the active layer to the second-conductivity-side first semiconductor layer. An impurity concentration in the second-conductivity-side first semiconductor layer is lower in a region nearer the electron barrier layer than in a region farther from the electron barrier layer.

Claim (Index 16):
The nitride-based light-emitting device according to  claim 15 ,\n wherein at least one of a seventh region in the first-conductivity-side second semiconductor layer adjacent to an interface between the first-conductivity-side second semiconductor layer and the first-conductivity-side third semiconductor layer and an eighth region in the first-conductivity-side third semiconductor layer adjacent to an interface between the first-conductivity-side third semiconductor layer and the first-conductivity-side second semiconductor layer forms at least one of a high-concentration impurity region and a composition change region, the high-concentration impurity region being a region doped with an impurity of a concentration higher than an impurity concentration in a ninth region in the first-conductivity-side second semiconductor layer adjacent to the seventh region and a tenth region in the first-conductivity-side third semiconductor layer adjacent to the eighth region, and the composition change region being a region in which a composition changes to interpolate an atomic composition from the ninth region to the tenth region.
