Niobium phosphide is aninorganic compound ofniobium andphosphorus with the chemical formula NbP.[1]
Sintering powdered niobium and phosphorus:
The compound is a unique material combining topological and conventional electronic phases. Its superfast electrons demonstrate extremely largemagnetoresistance, so NbP may be suitable for use in new electronic components.[2]
Niobium phosphide forms dark gray crystals of thetetragonal system,space groupI 41md, cell parametersa = 0.3334 nm,c = 1.1378 nm,Z = 4.[3]
It does not dissolve in water.
Niobium phosphide, liketantalum arsenide TaAs, is a topologicalWeyl semimetal.[4][5]
The compound is asemiconductor 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]
