EPITAXIAL GROWTH SUBSTRATE AND LIGHT-EMITTING ELEMENT USING SAME |
| 摘要 |
An epitaxial growth substrate includes a base member, and a concave-convex pattern having a plurality of concavities and a plurality of convexities and formed on the base member, wherein: each of the plurality of convexities has an elongated shape which extends while winding (waving) in a plane view; and the plurality of convexities in the concave-convex pattern have extending directions, bending directions and lengths which are non-uniform among the plurality of convexities. There are provided an epitaxial growth substrate which can be produced efficiently and which is capable of improving the light-emitting efficiency of a light-emitting element; and a light-emitting element using the epitaxial growth substrate. |

1. An epitaxial growth substrate comprising a base member, and a concave-convex pattern having a plurality of concavities and a plurality of convexities and formed on the base member, wherein:
(i) each of the plurality of convexities has an elongated shape which extends while winding in a plane view; and (ii) the plurality of convexities in the concave-convex pattern have extending directions, bending directions and lengths which are non-uniform among the plurality of convexities. |
