EPITAXIAL SUBSTRATE, SEMICONDUCTOR LIGHT-EMITTING DEVICE USING SUCH EPITAXIAL SUBSTRATE AND FABRICATION THEREOF

摘要

The invention provides an epitaxial substrate, a semiconductor light-emitting device using such epitaxial substrate and fabrication thereof. The epitaxial substrate according to the invention includes a crystalline substrate. In particular, a crystal surface of the crystalline substrate thereon has a plurality of randomly arranged nanorods. The plurality of nanorods is formed of oxide of a material different from that forms the crystalline substrate.
