Structure, Dielectric, and Electrical Characterization of 0.9(Bi0.5Na0.5TiO3) – 0.1(Bi0.5Sr0.25TiO3) (BNT-BST) Solid Solution for Capacitor Applications

Journal of Advanced College of Engineering and Management
Eco-friendly 0.9(Bi0.5Na0.5TiO3) - 0.1(Bi0.5Sr0.25TiO3) (BNT-BST) ceramics were synthesized via the solid-state reaction method. Structural, dielectric, and electrical properties were systematically studied. Rietveld refinement confirmed a pure rhombohedral perovskite structure with R3c symmetry. The dielectric constant peaked at 3456 @1kHz with a high

Bifunctional Design of Ferroelectric‐Order and Band‐Engineering in Cu:KTN Crystal for Extended Self‐Powered Photoelectric Response

Advanced Science, Volume 12, Issue 6, February 10, 2025.
This work proposes a bifunctional design strategy of ferroelectric‐order and electronic‐band to improve the photocurrent and extend the responsive range simultaneously. In a Cu‐doped KTa1−xNbxO3 perovskite crystal, a conductive channel is constructed by “head‐to‐head” ferroelectric domains, associated with the emergence of micrometer‐scale supercells ...
