First-principles investigations on electronic, elastic and optical properties of XC (X = Si, Ge, and Sn) under high pressurec

Several first principles calculations based on the density functional theory are conducted to explain the various electronic, elastic, as well as the optical properties of XC (X = Si, Ge, and Sn), as exhibited under extremely high pressure. The various technological applications of such compounds, as demonstrated in extreme environmental conditions are also analyzed.
