Abstract
An investigation on the structural, phonon, thermodynamic and elastic properties of Li2Te has been conducted using the norm-conserving psudopotentials within the local density approximation in the frame of the density functional theory (DFT) and the density functional perturbation theory (DFPT) in the ABINIT code. Our results demonstrate that Li2Te in the anti-fluorite structure phase keeps dynamically stable until 25 GPa. The elastic constants and thermodynamic quantities under high pressure are also calculated and discussed.
