Surface-emitting element

Abstract

To provide a surface-emitting element capable of suppressing occurrence of cracks due to an oxide confinement layer during driving and/or mounting. A surface-emitting element according to the present technology includes a first structure including a first semiconductor structure, a second structure stacked with the first structure and including a second semiconductor structure, and a third structure arranged between the first and second structures and including a light-emitting layer, in which an oxide confinement layer is provided between a surface of the first structure on a side opposite a light-emitting layer side and the light-emitting layer and/or between a surface of the second structure on a side opposite the light-emitting layer side and the light-emitting layer, the oxide confinement layer including a non-oxidized region, and an oxidized region surrounding at least a part of the non-oxidized region, and the oxidized region has a plurality of tapered portions whose thickness decreases toward inner peripheral ends. With the surface-emitting element according to the present technology, a surface-emitting element capable of suppressing occurrence of cracks due to an oxide confinement layer during driving and/or mounting can be provided.
