Silicon Carbide | SpringerLink
Silicon Carbide (SiC) is a compound semiconductor composed of equal parts silicon (Si) and carbon (C) atoms, arranged in a rigid 50–50 stoichiometry. Both Si and C atoms are tetravalent, meaning they have four valence electrons in their outermost shells, forming covalent bonds in a tetrahedral fashion to create the SiC crystal lattice.
