Crossover behavior in the magnetoresistance of thin flakes of the topological material ZrTe5
Zhijian Xie, Xinjian Wei, Xiaobin Qiang +9
ZrTe5 is a layered material that exhibits intricate topological effects. Intensive theoretically and experimental efforts have been devoted to try to understand the physics in this…
Electron-electron interactions and weak anti-localization in few-layer ZrTe5 devices
Zhijian Xie, Xinjian Wei, Shimin Cao +5
Much effort has been devoted to the electronic properties of relatively thick ZrTe5 crystals, focusing on their three-dimensional topological effects. Thin ZrTe5 crystals, on the o…
Barkhausen effect in the first order structural phase transition in type-II Weyl semimetal MoTe2
Chuanwu Cao, Xin Liu, Xiao Ren +7
We report the first observation of the non-magnetic Barkhausen effect in van der Waals layered crystals, specifically, between the Td and 1T' phases in type-II Weyl semimetal MoTe2…
Berry Curvature Enhanced Nonlinear Photogalvanic Response of Type-II Weyl Cone
Junchao Ma, Qiangqiang Gu, Yinan Liu +7
The experimental manifestation of topological effects in bulk materials under ambient conditions, especially those with practical applications, has attracted enormous research inte…
Raman Signatures of Broken Inversion Symmetry and In-plane Anisotropy in Type-II Weyl Semimetal Candidate TaIrTe4
Yinan Liu, Qiangqiang Gu, Yu Peng +9
The layered ternary compound TaIrTe4 is an important candidate to host the recently predicted type-II Weyl Fermions. However, a direct and definitive proof of the absence of invers…
Liquid phase mass production of air-stable black phosphorus/phospholipids nanocomposite with ultralow tunneling barrier
Qiankun Zhang, Yinan Liu, Jiawei Lai +9
Few-layer black phosphorus (FLBP), a recently discovered two-dimensional semiconductor, has attracted substantial attention in the scientific and technical communities due to its g…
