Cree uses silicon carbide for its <a href="http://www.mp-led.com" rel="nofollow"><strong>LED production</strong></a> , while some manufacturers such as Toshiba are using silicon substrates. GaN substrates offer a significant advantage for the growth of GaN-based layers, namely the much lower lattice mismatch between the layers and the substrate. However, GaN bulk crystals are difficult to grow, and commercially available GaN substrates are generally small in size and very expensive.
