The ground state properties of ferroelectric Bi2NbO5F structure are studied. The computed ground state properties and experimental results are consistent. The energy band structure of Bi2NbO5F compound below T-c shows that it is a ferroelectric semiconductor with narrow band gap of 0.0589 eV. Unfortunately, there is neither experimental nor theoretical electronic band structure study of Bi2NbO5F crystal in the literature, so we could not compare our results.eninfo:eu-repo/semantics/closedAccessDensity Functional TheoryElectronic Band StructureOptical PropertiesArticle274N/AQ310991103WOS:000421177200010
