Abstract
BaTiO3 properties can be enhanced to improve capacitor energy storage density through electric-field (E) dipole engineering at the nanoscale (E-DENS). E-DENS allows engineers to modify the internal E through dipole interactions. E-DENS of Ba[(Y3+,Ta5+)xTi1-2x]O3 with 0.0000 ≤ x ≤ 0.0500 are investigated by substituting Y3+-Ta5+ dipole pairs for Ti4+-Ti4+ non-dipolar pairs within the BaTiO3 structure. The Y3+ and Ta5+ ions are more polarizable than Ti4+ and are expected to increase the temperature at which the material becomes cubic and paraelectric. Room temperature XRD, UV-Vis-NIR, LCR, and resistivity analysis have been used to characterize Ba[(Y3+,Ta5+)xTi1-2x]O3 with 0.0000 ≤ x ≤ 0.0500.
