Résumé

The antimony compounds were spotlighted due to the growing interest of researchers for their use as wide gap semicon-
ductors. This is due to their physical properties, such as low electronic density, high thermal conductivity, wide band-gap
and large resistivity [1]. Boron compounds also have special physical properties, such as low ionicity [2–5], short bond
lengths [6], hardness [5], high melting points [7], and wide band gaps [8].
The different band gap bowings in antimony based III-V ternary alloys were calculated by Azzi et al. [9]. To the best
of our knowledge there have been no experimental or theoretical studies of the Al1-xBxSb ternary alloys. In this work,
the structural and electronic properties for AlSb, BSb and their ternary alloys have been studied using the full potential
linearized augmented plane wave (FP-LAPW) method.
The physical origin of the gap bowing has been studied [10] using the Zunger approach. The thermodynamic sta-
bility of the Al1-xBxSb alloys was investigated by calculating the excess enthalpy of mixing Hm; the calculated phase
diagram showed a broad miscibility gap with a high critical temperature. The thermal properties are calculated via the
quasi-harmonic Debye model.
