Thulium phosphide is an inorganic compound of thulium and phosphorus with the chemical formula TmP.[1][2]
Synthesis
[edit]Reaction of thulium metal with phosphorus:
- 4 Tm + P4 → 4 TmP
Physical properties
[edit]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]
Uses
[edit]The compound is a semiconductor used in high power, high frequency applications and in laser and other photo diodes.[dubious – discuss][1]
