Semiconductor Light Emitting Element

摘要

A semiconductor light emitting element include a semiconductor layer in which a first semiconductor layer, a second semiconductor layer, and a light emitting layer that is disposed between the first semiconductor layer and the second semiconductor layer are disposed. The first semiconductor layer has a step portion protruding more outwards than the light emitting layer and the second semiconductor layer. A plurality of first recesses is formed on side surfaces of the semiconductor layer not including the light emitting layer along a deposition direction of the semiconductor layer and along a direction intersecting with the deposition direction of the semiconductor layer and a plurality of second recesses is found on side surfaces of the semiconductor layer including the light emitting layer along the deposition direction of the semiconductor layer and along the direction intersecting with the deposition direction of the semiconductor layer.

1. A semiconductor light emitting element comprising a semiconductor layer in which a first semiconductor layer, a second semiconductor layer, and a light emitting layer that is disposed between the first semiconductor layer and the second semiconductor layer are disposed,
wherein the first semiconductor layer has a step portion protruding more outwards than the light emitting layer and the second semiconductor layer at at least a part of an outer peripheral portion thereof, and wherein a plurality of first recesses is formed on side surfaces of the semiconductor layer not including the light emitting layer on the basis of the step portion as a border along a deposition direction of the semiconductor layer and along a direction intersecting with the deposition direction of the semiconductor layer and a plurality of second recesses is formed on side surfaces of the semiconductor layer including the light emitting layer along the deposition direction of the semiconductor layer and along the direction intersecting with the deposition direction of the semiconductor layer.
