Long-Qing Chen, thus leading to the formation of the isolated ultrafine polar nanoclusters with varying sizes from 2 to 8 nm. These nanoclusters account for both considerable dielectric polarization and negligible polarization hysteresis. The present study opens a new realm of designing high-performance dielectric capacitors utilizing a large family of readily available linear dielectrics with very simple chemistry.

Hui Liu, guided by theoretical and phase-field simulations, 2024 Abstract: Dielectric capacitors are highly desired in modern electronic devices and power systems to store and recycle electric energy. However, by manipulating local symmetry breaking through introducing Ti/O defects. Atomic-scale characterizations confirm that these Ti/O defects lead to local symmetry breaking and local lattice strains,从而导致形成尺寸从2到8nm不等的分离的超细极性纳米团簇,这些Ti/O缺陷导致局部对称性破坏和局部晶格应变,在理论和相场模拟的指导下,这些纳米团簇解释了相当大的介电极化和可忽略的极化滞后,相关研究成果于2024年1月9日发表于国际一流学术期刊《美国化学会杂志》,在钛酸锶(SrTiO3)(一种简单化学成分的线性电介质)中显著实现9094%的超高效率和8590 J cm3的高能量密度的优越综合性能, 本期文章:《美国化学会志》:Online/在线发表 北京科技大学陈骏团队报道了具有简单成分的无铅薄膜的超高效率卓越储能, Peng Gao, Shiqi Xu,隶属于美国化学会, Zhenlin Luo。
