Electronic and Vibrational Excitations on the Surface of the Three-Dimensional Topological Insulator BiTeSe (x = 0, 2, 3)
A. Lee, H. -H. Kung, Xueyun Wang +2
We study surface states in the three-dimensional topological insulators BiTeSe (x = 0, 2, 3) by polarization resolved resonant Raman spectroscopy. By tracking the…
Coexisting Ferromagnetic-antiferromagnetic Phase and Manipulation in Magnetic Topological Insulator MnBi4Te7
Jianfeng Guo, Huan Wang, Xueyun Wang +9
Magnetic topological insulators (MTIs) have received a lot of attention due to the existence of various quantum phenomena such as quantum anomalous Hall effect (QAHE) and topologic…
Zero Poisson' s Ratio and Suppressed Mechanical Anisotropy in BP/SnSe Van der Waals Heterostructure: A First-principles Study
Qi Ren, Xingyao Wang, Yingzhuo Lun +2
Black phosphorene and its analogs have attracted intensive attention due to their unique puckered structures, anisotropic characteristics, and negative Poisson's ratio. The van der…
The Observation of Ferroelastic and Ferrielectric Domains in AgNbO3 Single Crystal
Wei Zhao, Zhengqian Fu, Jianming Deng +5
Compared to AgNbO3 based ceramics, the experimental investigations on the single crystalline AgNbO3, especially the ground state and ferroic domain structures, are not on the same…
Giant Polarization and Abnormal Flexural Deformation in Bent Freestanding Perovskite Oxides
Songhua Cai, Yingzhuo Lun, Dianxiang Ji +15
Recent realizations of ultrathin freestanding perovskite oxides offer a unique platform to probe novel properties in two-dimensional oxides. Here, we observed a giant flexoelectric…
Conductive Domain Walls in Non-Oxide Ferroelectrics Sn2P2S6
Jianming Deng, Xingan Jiang, Yanyu Liu +11
The conductive domain wall (CDW) is extensively investigated in ferroelectrics, which can be considered as a quasi-two-dimensional reconfigurable conducting channel embedded into a…
