(AlSb) is a semiconductor
of the group III-V family containing aluminium
. The lattice constant
is 0.61 nm. The indirect bandgap
is approximately 1.6 eV
at 300 K, whereas the direct band gap is 2.22 eV.
Its electron mobility is 200 cm²·V−1·s−1 and hole mobility 400 cm²·V−1·s−1 at 300 K. Its refractive index is 3.3 at a wavelength of 2 µm, and its dielectric constant is 10.9 at microwave frequencies.
AlSb can be alloyed with other III-V materials to produce the following ternary materials: AlInSb, AlGaSb and AlAsSb.
Aluminum antimonide is rather flammable because of the reducing tendency of the antimonide (Sb3−) ion. It burns to produce aluminum oxide and antimony trioxide.
