Шаблон:Chembox 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.[1]
History
Crystals of boron phosphide were synthesized by Henri Moissan as early as 1891.[2]
Appearance
Pure BP is almost transparent, n-type crystals are orange-red whereas p-type ones are dark red.[3]
Chemical properties
BP is not attacked by acids or boiling aqueous alkali water solutions. It is only attacked by molten alkalis.[3]
Physical properties
BP is known to be chemically inert and exhibit very high thermal conductivity.[4] Some properties of BP are listed below:
- lattice constant 0.45383 nm
- coefficient of thermal expansion 3.65Шаблон:E /°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)
- high thermal conductivity of ~ 460 W/(m·K) at room temperature[4]
