Eco-friendly transparent dielectric ceramics with superior energy storage properties are highly desirable in various energy-storage electronic devices, ranging from advanced pulse capacitors to electro-optical multifunctional devices. However, the collaborative improvement of and optical transparency KNN-based still remains challenging. To address this issue, multiple synergistic strategies proposed, such as refining grain size, introducing polar nanoregions, inducing a high-symmetry phase...
Abstract Dielectric capacitors with ultrahigh power density have emerged as promising candidates for essential energy storage components in electronic and electrical systems. They enable enhanced integration, miniaturization, lightweight design. However, the development of dielectric materials cutting-edge applications has been significantly limited by their low recoverable ( W rec ) efficiency η ), especially at moderate electric fields. In this study, we fabricated 0.85K 0.5 Na NbO 3...
Abstract Metal‐free halide perovskites, as a specific category of the perovskite family, have recently emerged novel semiconductors for organic ferroelectrics and promise wide chemical diversity ABX 3 structure with mechanical flexibility, light weight, eco‐friendly processing. However, after initial discovery 17 years ago, there has been no experimental information about their charge transport properties only one brief mention optoelectronic properties. Here, growth large single crystals...
Designing dielectric materials with the tremendous energy storage density is fundamentally important for developing pulse power capacitors. An effective approach was proposed to favorably modify properties (ESP) of Bi0.5Na0.5TiO3 ceramics using CaTiO3 incorporation. The breakdown strength effectively enhanced, and simultaneously relaxor behavior optimized lower remnant polarization, which resulted from decreased grains size introduction Ca2+ ion. Remarkably, at a doping level 0.2,...
Abstract Dielectric materials with ultrahigh permittivity are attracting attention due to the increasing demand for these types of microelectronics and energy storage applications. In this work, we successfully synthesized Zn‐doped CdCu 3 Ti 4 O 12 (CdCTO) ceramics low dielectric loss large via an ordinary mixed‐oxide technique. Remarkably, at a Zn doping level 0.10, 2.9 0.1 ceramic exhibited both decreased tangent ~0.058 > 4.0 × 10 , as well good frequency stability over wide range from...
