Harnessing dislocation motion using an electric field
Mingqiang Li, Yidi Shen, Kun Luo +4
Dislocations, line defects in crystalline materials, play an essential role in the mechanical[1,2], electrical[3], optical[4], thermal[5], and phase transition[6] properties of the…
Electric-field control of the nucleation and motion of isolated three-fold polar vertices
Mingqiang Li, Tiannan Yang, Pan Chen +12
Recently various topological polar structures have been discovered in oxide thin films. Despite the increasing evidence of their switchability under electrical and/or mechanical fi…
Engineering of Atomic-Scale Flexoelectricity at Grain Boundaries
Mei Wu, Xiaowei Zhang, Xiaomei Li +9
Flexoelectricity is a type of ubiquitous and prominent electromechanical coupling, pertaining to the response of electrical polarization to mechanical strain gradients while not re…
Dynamics of Polar Skyrmion Bubbles under Electric Fields
Ruixue Zhu, Zhexin Jiang, Xinxin Zhang +18
Room-temperature polar skyrmion bubbles that are recently found in oxide superlattice, have received enormous interests for their potential applications in nanoelectronics due to t…
Atomic Origin of Spin-Valve Magnetoresistance at the SrRuO3 Grain Boundary
Xujing Li, Li Yin, Zhengxun Lai +14
Defects ubiquitously exist in crystal materials and usually exhibit a very different nature than the bulk matrix, and hence, their presence can have significant impacts on the prop…
In situ TEM investigation of oxygen migration as a key mechanism for resistive switching in Pr0.7Ca0.3MnO3
Zhaoliang Liao, Peng Gao, Xuedong Bai +1
Low temperature growth Pr0.7Ca0.3MnO3 (PCMO) thin film showed high performance in electric field induced resistance switching (RS). To understand the micro-mechanism of RS in Metal…
