| Zusammenfassung: | A light emitting device is disclosed. The disclosed light emitting device includes a substrate, a UV light emitting semiconductor structure disposed on the substrate, and an intermediate layer interposed between the UV light emitting semiconductor structure and the substrate. The UV light emitting semiconductor structure includes a first conductivity-type semiconductor layer, a second conductivity-type semiconductor layer, and an active layer interposed between the first conductivity-type semiconductor layer and the second conductivity-type semiconductor layer, wherein the active layer has a multi quantum well structure including at least one period of a pair structure of a quantum barrier layer including Al x Ga (1-x) N (0 |
