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…
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…
Eightfold Fermionic Excitation in a Charge Density Wave Compound
Xi Zhang, Qiangqiang Gu, Haigen Sun +19
Unconventional quasiparticle excitations in condensed matter systems have become one of the most important research frontiers. Beyond two- and fourfold degenerate Weyl and Dirac fe…
Correlating the Electronic Structures of Metallic/Semiconductor MoTe2 Interface to its Atomic Structures
Bo Han, Chen Yang, Xiaolong Xu +8
Contact interface properties are important in determining the performances of devices based on atomically thin two-dimensional (2D) materials, especially those with short channels.…
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-environment-dependent thickness of ferroelastic domain walls
Mingqiang Li, Xiaomei Li, Yuehui Li +3
Domain walls are of increasing interest in ferroelectrics because of their unique properties and potential applications in future nanoelectronics. However, the thickness of ferroel…
