Abstract

Surface Reconstructions

In situ atomic-scale electron microscopy reveals that planar accumulation of oxygen vacancies in the subsurface TiO₂ layer of vacuum-annealed ferroelectric BaTiO₃ (001) surface mitigates the depolarization field by facilitating cooperative rumpling of surface and subsurface layers in a tail-to-tail dipole configuration. More details can be found in article number 2412781 by Jeehun Jeong, Jaejin Hwang, and co-workers.

亚表面氧空位介导的铁电BaTiO3（001）表面重构及去极化（ei）

原位原子尺度电子显微镜显示，真空退火铁电BaTiO3（001）表面的亚表面TiO2层中氧空位的平面积累通过促进表面和亚表面层在尾对尾偶极子构型中的协同皱巴巴来减轻去极化场。详细内容请参见《2412781号文章》（郑志勋、黄宰镇等人）。
