Boron phosphide (BP) is a chemical compound of boron and phosphorus. It is a semiconductor [2].

Contents

History

Crystals of boron phosphide have been synthesized by Henri Moissan as early as in 1891 [3].

Appearance

Pure BP is almost transparent, n-type crystals are orange-red whereas p-type ones are dark red [4].

Chemical properties

BP is not attacked by acids or boiling aqueous alkali water solutions. It is only attacked by molten alkalis.[4].
