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 19):
The nitride-based light-emitting device according to  claim 16 ,\n wherein an impurity concentration in the composition change region is 5\u00d710 17  cm \u22123  or more, and the composition change region is formed in a region from an interface adjacent to the composition change region to a distance of 10 nm or more from the interface.
