Chemical compound
Niobium phosphide is an inorganic compound of niobium and phosphorus with the chemical formula NbP.[ 1]
Synthesis
Sintering powdered niobium and phosphorus:
4
Nb
+
P
4
⟶ ⟶ -->
4
NbP
{\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.[ 2]
Niobium phosphide forms dark gray crystals of the tetragonal system , space group I 41md 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]
