The calculated band structure for KIO3 evidences that the crystal has a direct band gap with a value of 2.83 eV. The structural optimization has been performed. The real and imaginary parts of dielectric function, energy-loss function for volume and surface, and refractive index are calculated along the crystallographic axes.eninfo:eu-repo/semantics/closedAccessFerroelectricsDielectric ResponseElectronic Band StructureOptical PropertiesArticle2310Q2Q224052412WOS:000265940800012
