SEMICONDUCTOR LIGHT-EMITTING ELEMENT

摘要

A semiconductor light-emitting element according to the present invention includes: an n-type nitride semiconductor layer 21; a p-type nitride semiconductor layer 23; an active layer region 22 which includes an m-plane nitride semiconductor layer and which is interposed between the n-and p-type nitride semiconductor layers; an n-type electrode 30 which is electrically connected to the n-type nitride semiconductor layer; a p-type electrode 40 which is electrically connected to the p-type nitride semiconductor layer; a light-emitting face, through which polarized light that has been produced in the active layer region is extracted out of this element; and a striped structure 50 which is provided for the light-emitting face and which has a plurality of projections that run in a direction that defines either an angle of 5 degrees to 80 degrees or an angle of -80 degrees to -5 degrees with respect to the a-axis direction of the m-plane nitride semiconductor layer.
