General description

Silicon carbide (SiC) is a semiconducting material with closed packed stacking of double layers of silicon and carbon. It has excellent thermo-mechanical and electrical properties that make it useful in a variety of electronic and optoelectronic applications.

Application

SiC is majorly used as a base material for applications such as micro-structures, opto-electronic devices (light emitting diodes (LEDs), UV detectors), high temperature electronics (nuclear electronics), and high frequency devices.
