摘要: Abstract A theoretical investigation on the structural, phonon, elastic and thermodynamic properties of ordered Ge 0.5 Sn cubic alloy has been conducted using norm-conserving psudopotentials within local density approximation in frame functional theory (DFT) perturbation (DFPT) ABINIT code. We present that zinc-blende phase keeps dynamically stable until 9 GPa. The constants quantities as a function pressure temperature are also reported.
