1Structures and electronic properties of domain walls in Bi FeO3 thin films显示文摘Domain walls(DWs)in ferroelectrics are atomically sharp and can be created;erased,and reconfigured within the same physical volume of ferroelectric matrix by external electric fields.They possess a myriad of novel properties and functionalities that are absent in the bulk of the domains,and thus could become an essential element in next-generation nanodevices based on ferroelectrics.The knowledge about the structure and properties of ferroelectric DWs not only advances the fundamental understanding of ferroelectrics,but also provides guidance for the design of ferroelectric-based devices.In this article,we provide a review of structures and properties of DWs in one of the most widely studied ferroelectric systems,BiFeO3 thin films.We correlate their conductivity and photovoltaic properties to the atomic-scale structure and dynamic behaviors of DWs.Huaixun Huyan Linze Li Christopher Addiego Wenpei Gao Xiaoqing Pan 2019National Science Review2019,6,4:1
2Emergent properties at oxide interfaces controlled by ferroelectric polarization显示文摘Ferroelectric materials are characterized by the spontaneous polarization switchable by the applied fields,which can act as a“gate”to control various properties of ferroelectric/insulator interfaces.Here we review the recent studies on the modulation of oxide hetero-/homo-interfaces by ferroelectric polarization.We discuss the potential applications of recently developed four-dimensional scanning transmission electron microscopy and how it can provide insights into the fundamental understanding of ferroelectric polarization-induced phenomena and stimulate future computational studies.Finally,we give the outlook for the potentials,the challenges,and the opportunities for the contribution of materials computation to future progress in the area.Fan Ye Yi Zhang Christopher Addiego Mingjie Xu Huaixun Huyan Xiaobing Ren Xiaoqing Pan 2021npj Computational Materials2021,,1:0
