Aluminium antimonide (AlSb) decomposes slowly to Al and Sb at room temperature. | [Production Methods]
To grow single crystals, Al and Sb are mixed stoichiometrically in the Al2O3 boat and melted, followed by pulling up of a single crystal using the Czochralski method. Melted Al is oxidized easily and various methods, like rotation of a crucible, are considered to remove the oxide.1 The speed of pulling up is better to be smaller than 7.5 cm/h. High-grade graphite crucible is often used, but p-type impurities might be produced by the reaction of Al and C. Zone refining using the Al2O3 boat or floating zone refining is possible, but a remarkable removal of impurities like Si and Ge is not expected. | [Structure and conformation]
The space lattice of AlSb belongs to the cubic system, and its zinc blend-type structure has a lattice constant of a=0.6136 nm and Al–Sb=0.266 nm.
