摘要: Abstract We have investigated the structural parameters, electronic structure and optical properties of orthorhombic SrZrO 3 using plane-wave ultrasoft pseudopotential technique based on first-principles density-functional theory (DFT). Our calculated parameters are in good agreement with previous theoretical experimental data. Band structure, density states chemical bonding been systematically studied. Furthermore, complex dielectric function, refractive index, extinction coefficient, reflectivity, absorption loss function conductivity calculated, which show an anisotropy components polarization directions (100), (010) (001).
