- W4313406943 abstract "In this work, we have investigated the effect of chromium (Cr) doping on the structural, electronic and optical properties of the cubic phase of BaTiO3 using first-principles calculations. Applying the GGA + U approximation, the lattice parameters as well as the band gaps of the undoped and doped phase of BaTiO3 are in fairly good agreement with the experimental data, confirming the validity of our model. Furthermore, the chemical bonding analysis underlines the ionic character of Ba–O bonds and the covalent nature of Ti–O and Cr–O bonds. Additionally, the investigation of the optical properties using the Hubbard U-potential correction provided good agreement with the experimental data in the broad energy ranges. We have also demonstrated that the substitution of chromium on the Ti site, through the calculation of both electronic and optical properties, leads to the appearance of defects close to the Fermi level, allowing the appearance of the asymmetry of the BaTi1-xCrxO3 system. As a result, the calculated total magnetic moment is 1.6038 μB, indicating that doping with Cr renders the BaTi1-xCrxO3 system ferromagnetic. Therefore, this work demonstrates that Cr-doped BaTiO3 could reasonably constitute a new class of perovskite materials for magneto-optoelectronic applications." @default.
