DFT-based calculations provide an accurate prediction of the atomic and electronic structure of these systems. The computed lattice parameter is linearly correlated with the experimental result in the Co concentration ranging from 1.0 to 5.0%. For higher Co concentrations, the theoretical-experimental analysis of the results indicates that the dopant is likely to be preferentially present at surface sites. The analysis of the electronic structure supports the experimental assignment of Co2+ for the doped material. Experiments and theory find that the presence of Co has a limited effect on the material band gap.9 p.application/pdfengcc-by (c) Voccia, Maria et al., 2024http://creativecommons.org/licenses/by/3.0/es/Difracció de raigs XOxigenCobaltX-rays diffractionOxygenCobaltinfo:eu-repo/semantics/article7552942025-07-21info:eu-repo/semantics/openAccess
