摘要： A semiconductor light-emitting element with a counter electrode structure can include a first electrode including at least one linear first electrode piece that is disposed on a surface of a first semiconductor layer close to the support substrate and in ohmic contact with the first semiconductor layer, a second electrode including at least one linear second electrode piece that is disposed on a surface of a second semiconductor layer and in ohmic contact with the second semiconductor layer. A plurality of conical projections can be formed on the second semiconductor layer. The first electrode piece and the second electrode piece can be disposed soas not to overlap with each other in a stacked direction of the semiconductor light-emitting stacked body but to be parallel with each other when viewed from above.

摘要： A semiconductor light-emitting apparatus that has high luminous efficiency and a high breakdown voltage as well as reduced breakdown voltage variation among lots. The semiconductor light-emitting apparatus includes a first clad layer and a second clad layer. An average dopant concentration of the second clad layer is lower than that of the first clad layer. The light-emitting apparatus also includes an active layer having an average dopant concentration of 2×1016 to 4×1016 cm−3. The active layer is made of (AlyGa1-y)xIn1-xP (0
