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…
Atomically-Precise, Custom-Design Origami Graphene Nanostructures
Hui Chen, Xian-Li Zhang, Yu-Yang Zhang +8
The construction of atomically-precise carbon nanostructures holds promise for developing novel materials for scientific study and nanotechnology applications. Here we show that gr…
Promising Ferroelectricity in 2D Group IV Tellurides: a First-Principles Study
Wenhui Wan, Chang Liu, Wende Xiao +1
Based on the first-principles calculations, we investigated the ferroelectric properties of two-dimensional (2D) Group-IV tellurides XTe (X=Si, Ge and Sn), with a focus on GeTe. 2D…
Stacking-dependent electronic property of trilayer graphene epitaxially grown on Ru(0001)
Yande Que, Wende Xiao, Hui Chen +3
The growth, atomic structure, and electronic property of trilayer graphene (TLG) on Ru(0001) were studied by low temperature scanning tunneling microscopy and spectroscopy in combi…
