Because it has a high melting point, it is used in high performance brake discs, as a the matrix for particulate filters in engines, and because it is a semiconductor in high temperature and high voltage applications.\u00a0 Come to think of it, silicon carbide is also used as an abrasive in sand paper.<\/p>\n<p>Today you can add terahertz generator to the list. Jared Straight and pals from Cornell University bombarded silicon carbide with infrared light pulses and found that it in response, it emitted coherent radiation with a frequency of between 1 and 6 Thz.<\/p>\n<p>That&#8217;s handy because the current best way to make terahertz radiation in this way is to bombard galium arsenide or zinc tellurium with infrared light.
