Thulium phosphide is an inorganic compound of thulium and phosphorus with the chemical formula TmP.{{cite web |title=Thulium Phosphide |url=https://www.americanelements.com/thulium-phosphide-12037-68-2 |publisher=American Elements |access-date=22 December 2021 |language=en}}{{cite book |title=Toxic Substances Control Act (TSCA) Chemical Substance Inventory |date=1979 |publisher=U.S. Government Printing Office |page=86 |url=https://books.google.com/books?id=EwXoYmUt_B0C&dq=Thulium+phosphide&pg=RA1-PA86 |access-date=22 December 2021 |language=en}}
Synthesis
Reaction of thulium metal with phosphorus:
::4 Tm + P4 → 4 TmP
Physical properties
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.{{cite conference |last1=Bhajanker |first1=Sanjay |last2=Srivastava |first2=Vipul |last3=Sanyal |first3=Sankar P. |title=Structural and mechanical properties of some thulium pnictides under pressure |url=https://aip.scitation.org/doi/abs/10.1063/1.4810462 |conference=Recent Trends in Applied Physics and Material Science: Ram 2013 |series=AIP Conference Proceedings |access-date=22 December 2021 |pages=785–786 |doi=10.1063/1.4810462 |date=3 June 2013|volume=1536 |issue=1 |bibcode=2013AIPC.1536..785B |url-access=subscription }}{{cite journal |last1=Lin |first1=C.
