Scanning electron micrograph of with ZnO sintered at for .
Dependence of on the sintering temperature of (BCT) samples synthesized with and without 2% ZnO sintering agent.
Dependence of dielectric constant on sintering temperature for (BCT) samples synthesized with and without 2% ZnO sintering agent.
Ball and stick model of (a) and (b) . Solid black balls are Zn in (a) and Cd in (b). The distortion relative to the bond-centered configuration has been amplified by a factor of 5 to more clearly show the distortion, in particular, the buckling of the Ta–O–Cd bond.
Energy as a function of the generalized coordinate . parametrizes the collective displacement of the O atoms; corresponds to the high-symmetry position of the oxygen atom between the Cd and Ta atoms; to the minimum energy configuration given in Table II.
Electronic band structure of (a) and (b) as calculated by the linear muffin tin orbital method within the local density functional approximation.
The lattice constants of powder samples fit to the cubic and hexagonal structure.
Table of lattice positions in Cartesian coordinates. Note: The dimensions are scaled to the cubic unit cell dimensions.
