}}Boron phosphide (BP) (also referred to as boron monophosphide, to distinguish it from boron subphosphide, B12P2) is a chemical compound of boron and phosphorus. It is a semiconductor.[3]

History

Crystals of boron phosphide were synthesized by Henri Moissan as early as in 1891.[4]

Appearance

Pure BP is almost transparent, n-type crystals are orange-red whereas p-type ones are dark red.[5]

Chemical properties

BP is not attacked by acids or boiling aqueous alkali water solutions. It is only attacked by molten alkalis.[5]

Physical properties

Some properties of BP are listed below:[1][5]

  • lattice constant 0.45383 nm
  • coefficient of thermal expansion 3.65{{e|−6}} /°C (400 K)
  • heat capacity CP ~ 0.8 J/(g·K) (300 K)
  • Debye temperature = 985 K
  • Bulk modulus 152 GPa
  • relatively high microhardness of 32 GPa (100 g load).
  • electron and hole mobilities of a few hundred cm2/(V·s) (up to 500 for holes at 300 K)
  • record-high room temperature thermal conductivity of 460 W/mK was reported for very high quality single crystals
