What is Theoretical study on the physical properties of synthesized SrMO~3~ (M = Hf and Pt) oxide perovskites using DFT about?

We investigated the physical behavior of SrMO~3~ (M = Hf and Pt) compounds, which are strontium-based oxide perovskites. We utilized the WIEN2k software to simulate and investigate their physical properties. The structural stability of SrHfO~3~ and SrPtO~3~ was verified using the Birch–Murnaghan equation of states for optimization. We also checked the elastic stability through the computation of elastic constants using the IRelast software. Our results indicate the stability of these compounds and showed their anisotropic, ductility, scratch-resistive, and plastic strain-resistant characteristics. Using the TB-mBJ potential approach, we determined that SrHfO~3~ is an insulator, whereas SrPtO~3~ is a metal in nature. The density of states computations was used to find the band structure as well as the contribution of different electronic states. Optical property research was conducted using the band gap energies of these substances. Our findings suggest that these crystals have low energy absorption and reflectivity of up to 65%, making them suitable for use in high-frequency UV devices. Specifically, SrHfO~3~ is more transparent before the energy point 2.80 eV, while the compound S
