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…
Antiphase boundary in CHNHPbI repels charge carriers while promotes fast ion migrations
Shulin Chen, Changwei Wu, Qiuyu Shang +9
Defects in organic-inorganic hybrid perovskites (OIHPs) greatly influence their optoelectronic properties. Identification and better understanding of defects existing in OIHPs is a…
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…
Transmission electron microscopy of organic-inorganic hybrid perovskites: myths and truths
Shulin Chen, Ying Zhang, Jinjin Zhao +8
Organic-inorganic hybrid perovskites (OIHPs) have attracted extensive research interest as a promising candidate for efficient and inexpensive solar cells. Transmission electron mi…
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…
