Influence of Grain Size on Dielectric Behavior in Lead-Free 0.5 Ba(ZrTi)O-0.5 (BaCa)TiO Ceramics.

Fine-tuning of grain sizes can significantly influence the interaction between different dielectric phenomena, allowing the development of materials with tailored dielectric resistivity. By virtue of various synthesis mechanisms, a pathway to manipulate grain sizes and, consequently, tune the material's dielectric response is revealed. Understanding these intricate relationships between granulation and dielectric properties can pave the way for designing and optimizing materials for specific applications where tailored dielectric responses are sought.

Experimental Band Structure of Pb(Zr,Ti)O : Mechanism of Ferroelectric Stabilization.

Pb(Zr,Ti)O (PZT) is the most common ferroelectric (FE) material widely used in solid-state technology. Despite intense studies of PZT over decades, its intrinsic band structure, electron energy depending on 3D momentum k, is still unknown. Here, Pb(Zr Ti )O using soft-X-ray angle-resolved photoelectron spectroscopy (ARPES) is explored.
