Silicon Carbide is used as substrate for GaN-epitaxy to produce LEDs in the blue/UV range of the spectrum. SiC is the material of choice because it offers low lattice mismatch for III-nitride epitaxial layers and high thermal conductivity (important for lasers).

Blue LEDs on SiC-basis have been commercially available for several years now. The next important step will be the development of blue SiC-laser-diodes, which can be used to increase data storage capacity among many other applications. The use of SiC-based UV- diodes may also find various applications, i.e. monitoring of combustion processes, all sorts of UV-detection while detector is almost solar-blind.
