Direct observation of local antiferroelectricity induced phonon softening at a SrTiO3 defect
Bo Han, Ruochen Shi, Huining Peng +7
Defects in oxides usually exhibit exotic properties that may be associated with the local lattice dynamics. Here, at atomic spatial resolution, we directly measure phonon modes of…
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…
Creating topological polar structure in a nonpolar matter
Adeel Y. Abid, Yuanwei Sun, Xu Hou +15
Nontrivial topological structures offer rich playground in condensed matter physics including fluid dynamics, superconductivity, and ferromagnetism, and they promise alternative de…
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…
Atomic-scale structure and chemistry of YIG/GGG Interface
Mengchao Liu, Lichuan Jin, Jingmin Zhang +4
Y3Fe5O12 (YIG) is a promising candidate for spin wave devices. In the thin film devices, the interface between YIG and substrate may play important roles in determining the device…
Two-Carrier Transport Induced Hall Anomaly and Large Tunable Magnetoresistance in Dirac Semimetal Cd3As2 Nanoplates
Cai-Zhen Li, Jin-Guang Li, Li-Xian Wang +4
Cd3As2 is a model material of Dirac semimetal with a linear dispersion relation along all three directions in the momentum space. The unique band structure of Cd3As2 makes it with…
