Silicon nitride - Wikipedia
Silicon nitride is a chemical compound of the elements silicon and nitrogen. Si 3N 4 is the most thermodynamically stable of the silicon nitrides. Hence, Si 3N 4 is the most commercially important of the silicon nitrides[4] when referring to the term "silicon nitride". It is a white, high-melting-point solid that is relatively chemically inert

Is Graphitic Silicon Carbide (Silagraphene) Stable? | …
Graphene is considered to be the most likely candidate for the postsilicon era; however, the problem with its zero band gap is challenging to overcome. A close relative of silicon, silicon carbide is expected to have a stable 2D polymorph which happens to be a wide-gap semiconductor. Unfortunately, the so-called silagraphene has proven to be elusive. To date, neither theoretical nor
