Optical bulk-boundary dichotomy in a quantum spin Hall insulator
Junfeng Han, Pengcheng Mao, Hailong Chen +17
The bulk-boundary correspondence is a key concept in topological quantum materials. For instance, a quantum spin Hall insulator features a bulk insulating gap with gapless helical…
Quantum transport evidence of the boundary states and Lifshitz transition in BiBr
Dong-Yun Chen, Dashuai Ma, Junxi Duan +4
The quasi-one-dimensional van der Waals compound BiBr was recently found to be a promising high-order topological insulator with exotic electronic states. In this paper, we…
Ultralong carrier lifetime of topological edge states in a-Bi4Br4
Pengcheng Mao, Junfeng Han, Jingchuan Zheng +13
The rising of quantum spin Hall insulators (QSHI) in two-dimensional (2D) systems has been attracting significant interest in current research, for which the 1D helical edge states…
Observation of the Topologically Originated Edge States in large-gap Quasi-One-Dimensional a-BiBr
Pengcheng Mao, Maoyuan Wang, Dashuai Ma +16
Two-dimensional topological insulator features time-reversal-invariant spin-momentum-locked one-dimensional (1D) edge states with a linear energy dispersion. However, experimental…
Robust edge photocurrent response on layered Type II Weyl semimetal WTe2
Qinsheng Wang, Jingchuan Zheng, Yuan He +16
Photo sensing and energy harvesting based on exotic properties of quantum materials and new operation principles have great potentials to break the fundamental performance limit of…
Type-III Weyl Semimetals: (TaSe4)2I
Xiao-Ping Li, Ke Deng, Botao Fu +6
Weyl semimetals have been classified into type-I and type-II with respect to the geometry of their Fermi surfaces at the Weyl points. Here, we propose a new class of Weyl semimetal…
