Chemical compound
Niobium phosphide is an inorganic compound of niobium and phosphorus with the chemical formula NbP.[1]
Synthesis
Sintering powdered niobium and phosphorus:
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]
