Thulium phosphide is an inorganic compound of thulium and phosphorus with the chemical formula TmP. [1] [2]
Reaction of thulium metal with phosphorus:
The dense phosphide film will prevent further reactions inside the metal. After etching gallium arsenide, an epitaxial layer of thulium phosphide can be grown on the surface to obtain a TmP/GaAs heterostructure. [3] [4]
The compound forms crystals of a cubic system, space group Fm3m. [5] TmP crystallizes in a NaCl-type structure at ambient pressure. [6]
The compound is a semiconductor used in high power, high frequency applications and in laser and other photo diodes.[ dubious – discuss] [1]
