Abstract
), an extraordinarily short discharge time of 97 ns, a high Vickers hardness rating of approximately 8.23 GPa, and outstanding thermal and frequency stability. This enhancement can be attributed to the synergistic effect at all scales from atomic substitution, polar nano regions, submicrometer grain, and sample thickness. Consequently, this panoscopic approach has effectively demonstrated the potential to enhance the ESP of dielectric ceramics.
