Niobium phosphide is an inorganic compound of niobium and phosphorus with the chemical formula NbP.

Synthesis

Sintering powdered niobium and phosphorus:

${\displaystyle {\ce {4Nb + P4 -> 4NbP}}}$

Physical properties

The compound is a unique material combining topological and conventional electronic phases. Its superfast electrons demonstrate extremely large magnetoresistance, so NbP may be suitable for use in new electronic components.

Niobium phosphide forms dark gray crystals of the tetragonal system, space group I 41md, cell parameters a = 0.3334 nm, c = 1.1378 nm, Z = 4.

It does not dissolve in water.

Niobium phosphide, like tantalum arsenide TaAs, is a topological Weyl semimetal.

Uses

The compound is a semiconductor used in high power, high frequency applications and in laser diodes.
