"Silicon carbide (SiC)'s 2D allotrope has large direct band gap of 2.5 eV and high chemical versability,... 

synthesize monocrystalline epitaxial monolayer honeycomb SiC on top of ultrathin transition metal carbide films placed on SiC substrates... SiC decomposes, metal carbide remains intact and Si and C atoms migrate to surface... ceramic plates, bulletproof vests... SiC is semiconductor, a material that has a moderate electrical conductivity, ranging between that of conductors and insulators"
