Silicon carbide (SiC), also known as carborundum is an exceedingly hard, synthetically produced crystalline compound of silicon and carbon. It occurs in nature as the extremely rare mineral Moissanite. Until 1929, silicon carbide was the hardest synthetic material known. It has a hardness rating of 9, close to that of diamond. In addition to hardness, […]
Two-dimensional (2D) atomic crystals, especially graphene, have received much attention. However, the main shortcoming of graphene is its zero band gap. Silicon carbide, composed of silicon and carbon, is a typical wurtzite compound semiconductor, with more than 250 alloy types.
