Electronic Structure and Defect Chemistry of Tin(II ...

Tin(II) complex oxides have unique valence band structures due to the contribution of the Sn 5sp orbitals. We investigate the fundamental electronic, optical, and defect properties of tin(II) niobate (SnNb 2 O 6) via first-principles calculations and the characterization of epitaxial thin films.The calculations reveal its characteristic valence band structure similar to that of SnO.
