Abstract:The structural, mechanical, thermal, and electronic structure properties of lead-free vacancy-ordered perovskites A2SnCl6 (A = Cs, Rb) were investigated by first-principles calculations under pressure in the DFT framework. DFT is used to study the effect of pressure (0–40 GPa) on these properties of A2SnCl6 (A = Cs, Rb) perovskites. The mechanical parameters show that these two perovskites in nature are mechanically stable, anisotropic, and ductile. It is shown that, as pressure increases, the electronic band … Show more
