Optical substrate, semiconductor light-emitting element and method of manufacturing semiconductor light-emitting element |
| abstract |
An optical substrate that includes a substrate main body and a concave-convex structure which is formed in a part or a whole of a surface of the substrate main body, nwherein the concave-convex structure includes: na first concave-convex structure (L) that is provided on a main surface of the substrate main body and that is formed with a plurality of convex portions and concave portions having a first average interval (PL); and na second concave-convex structure (S) that is provided on a surface of at least one of the convex portion and the concave portion forming the first concave-convex structure (L) and that is formed with a plurality of convex portions and concave portions having a second average interval (PS), and n na ratio (PL/PS) between the first average interval (PL) and the second average interval (PS) is more than 1 but equal to or less than 2000. nWhen the optical substrate is used in a semiconductor light-emitting element, dislocations in a semiconductor layer are dispersed to reduce the dislocation density, and thus internal quantum efficiency IQE is improved, and a waveguide mode is removed by light scattering and thus the light the extraction efficiency LEE is increased, with the result that the efficiency of light emission of the semiconductor light-emitting element is enhanced. |
