    First-principles investigation of Ra doping effects on structural, electronic, and optical properties of BaTiO3 perovskite for solar cell applications by Sonia Chahar, Krishna Kumar Mishra, Rajnish Sharma

    Published 2025-01-01
    “…The orbital nature of Ba, Ra, Ti, and O atoms was analyzed through density of state and projected density of state analyses for pure BaTiO _3 , RaTiO _3 , and Ra-doped BaTiO _3 (x = 0.25, 0.50, 0.75). The optical properties of these materials, including dielectric constant, susceptibility, optical conductivity, polarizability (real and imaginary), absorption coefficient, refractive index, extinction coefficient, and reflectivity, were thoroughly examined. …”
