“…The iii-v semiconductor ternary alloys, has attracted attention of researchers in recent years [1][2][3][4][5]. They are good candidates for many device applications such as: high-speed electronic and long wave length photonic devices because of their band gaps cover a wide spectral range [6,7].…”

InvestIgatIon on structural, electronIc, thermal and thermoelectrIc ProPertIes of al 0.25 B 0.75 as alloy under Pressure, Based on densIty functIonal theory (dft)in this paper, structural, electronic, thermal, and thermoelectric properties of Al 0.25 B 0.75 As alloy, under pressures 0 GPa, 4 GPa and 8 GPa, have been calculated. The value of band gap at present work under 0 GPa, with GGA(PBe) exchange-correlation potential, is very close to other works with TB-mBJ method. This is a result of equal selection of muffin-tin radius spheres that are bigger than usual size for Al and B atoms. The values of band gap decrease by increasing pressure. in thermal properties, phonon contribution of heat capacity at constant volume and debye temperature have been calculated in the range of 0K to 1000K temperatures and under 0 GPa, 4 GPa and 8 GPa pressures. Thermoelectric properties, under the same pressures and in the range of 100K to 1000K temperatures have been investigated.
