The inherent properties of silicon carbide as a wide band-gap semiconductor has enabled its use in most power devices for high frequency, high power, and high temperature appliions. However, its appliion in optical devices has been hampered since it is an indirect-band-gap semiconductor which shows rather weak luminescence.
