More Information
Summary:A patterned substrate includes a substrate body having a surface and a plurality of patterned structures periodically arranged on the surface of the substrate body, where each of the patterned structures includes a first portion formed on the surface of the substrate body, and a second portion formed on the first portion, and where any two adjacent ones of the patterned structures are spaced apart from one another by a minimum distance of not greater than 0.1 μm. A light-emitting diode includes the patterned substrate and a semiconductor epitaxial structure formed thereon. A process for preparing the patterned substrate and a process for preparing the light-emitting diode are also disclosed.
