Niobium phosphide is an inorganic compound of niobium and phosphorus with the chemical formula NbP. [1]

Contents

Synthesis

Sintering powdered niobium and phosphorus:

4 Nb + P4 → 4 NbP

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. [2]

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. [3]

It does not dissolve in water.

Niobium phosphide, like tantalum arsenide TaAs, is a topological Weyl semimetal. [4] [5]

Uses

The compound is a semiconductor used in high power, high frequency applications and in laser diodes. [1]

Niobium phosphate is also being explored specifically for replacing copper as an ultra-thin nanometer film, where it exhibits much lower resistance than the conventional metal. [6]
