Abstract:
1. A nitride-based compound semiconductor light emitting device including: an n-electrode, a p-electrode, and an n-type compound semiconductor layer, an active layer and a p-type compound semiconductor layer respectively formed between the n-electrode and the p-electrode, wherein the n-electrode comprises: a first electrode layer formed of at least one element selected from the group consisting of Ir, Fe, Ru, and Os, and a second electrode layer formed on the first electrode layer using a conductive material containing at least one element selected from the group consisting of V, Nb, Hf, Re, and Pb, wherein the first electrode layer of the n-electrode directly or indirectly contacts the n-type compound semiconductor layer and the first electrode layer is disposed between the second electrode layer and the n-type compound semiconductor layer, wherein the n-electrode is disposed closer to the n-type compound semiconductor layer than the p-type compound semiconductor layer, and wherein the first electrode layer and the second electrode layer are sequentially stacked on the n-type compound semiconductor layer.
