Sic sapphire

Webmaterial is the substrate. Four substrates are mentioned, GaN itself, SiC, Sapphire and silicon. Of course, the ideal substrate would be GaN itself, bulk GaN, since GaN shows significant properties superior to other materials. Bulk GaN allows for homo-epitaxy without any mismatches between substrate and WebSiC substrates are higher cost than Si but have been successfully used for LED manufacturing processes. Much of the LEDs produced by Cree (who also manufacture SiC substrates) use this type of substrate. However, the higher cost and limited availability of 6 inch SiC material means that the majority of LED producers use sapphire.
