Silicon nitride is a chemical compound of the elements silicon and nitrogen. Si 3 N 4 (Trisilicon tetranitride) is the most thermodynamically stable and commercially important of the silicon nitrides, [6] and the term ″Silicon nitride″ commonly refers to this specific composition.
A reported silicon phosphide is Si 12 P 5 (no practical applications), [89] [90] formed by annealing an amorphous Si-P alloy. The arsenic–silicon phase diagram measured at 40 Bar has two phases: SiAs and SiAs 2. [91] The antimony–silicon system comprises a single eutectic close to the melting point of Sb. [92] The bismuth system is a ...

A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
Hexagonal boron nitride, which adopts a layered structure, is a useful high-temperature lubricant akin to molybdenum disulfide. Nitride compounds often have large band gaps, thus nitrides are usually insulators or wide-bandgap semiconductors; examples include boron nitride and silicon nitride.
