Design of a low band gap oxide ferroelectric: Bi $_{6}$ Ti $_{4}$ O $_{17}$

Bo Xu, David J. Singh, Valentino R. Cooper +1

A strategy for obtaining low band gap oxide ferroelectrics based on charge imbalance is described and illustrated by first principles studies of the hypothetical compound Bi $_{6}$ Ti$…

Effect of $A$ -site size difference on polar behavior in $M$ BiScNbO $_{6}$ ,( $M$ $=$ Na, K and Rb): Density functional calculations

S. Takagi, A. Subedi, V. R. Cooper +1

We investigate the effect of $A$ -site size differences in the double perovskites BiScO $_{3}$ - $M$ NbO $_{3}$ ( $M$ $=$ Na, K and Rb) using first-principles calculations. We find that the pol…

Polar behavior of double perovskite (Bi,Pb)ZnNbO6 and (Bi,Sr)ZnNbO6: Density functional calculations

S. Takagi, A. Subedi, D. J. Singh +1

The polar behavior of double perovskite (Bi,Pb)ZnNbO $_{6}$ and (Bi,Sr)ZnNbO $_{6}$ was investigated using first principles density functional calculations within the local density appro…
