Ionic-Covalent Bonding in Crystals [PDF]

open access: bronzeNature, 1961
GOODMAN'S comments on our recent article1 in no way affect our views on the subject of ionic-covalent bonding as outlined there. Since it is obvious, however, that Goodman is misinterpreting these views, we should like to stress once again the following points:

Ionic-Covalent Bonding in Crystals [PDF]

open access: bronzeNature, 1960
AN attempt1 to resolve misunderstandings regarding ionic-covalent bonding in solids has been criticized in a recent article by Mooser and Pearson2. It should be pointed out, however, that their discussion of formal ionicity is limited to the simple and well-known case of atoms which each contribute one electron to a two-electron bond, and cannot be ...

Theoretical investigation of structural, electronic, dielectric and optical characteristics of cubic perovskite BaCeO3 [PDF]

open access: yesProcessing and Application of Ceramics, 2021
Structural, electronic and optical parameters of a cubic perovskite BaCeO3 were calculated using FP-LAPW with WIEN2K code. The calculated band structure confirmed the semiconducting behaviour of BaCeO3 with an indirect band gap of 2.33 eV.
