Boron phosphide (BP) is a chemical compound of boron and phosphorus. It is a semiconductor .
History
Crystals of boron phosphide have been synthesized by Henri Moissan as early as in 1891 .
Appearance
Pure BP is almost transparent, n-type crystals are orange-red whereas p-type ones are dark red .
Chemical properties
BP is not attacked by acids or boiling aqueous alkali water solutions. It is only attacked by molten alkalis..
Physical properties
- coefficient of thermal expansion ~3x10 /°K
- heat capacity CP ~ 0.8 J/(g*K) (300 K)
- Debye temperature = 1000 K
- relatively high microhardness of 32 GPa (100 g load).
- electron and hole mobilities of few hundred cm/(V*s) (up to 500)
