Effect of doping on the crystal structure and dielectric properties of the Aurivillius phase CaBi4Ti4O15
The effect of doping on the crystal structure and dielectric properties of layered perovskite-type bismuth oxide CaBi4Ti4O15 (Aurivillius phase) has been investigated. Partial substitution both in A (Bi by Na, Pb) and B (Ti by Cr, V, Re) sites leads to changes in the crystal structure parameters and dielectric constants, depending on the dopant type and content.
