Exceptional Tunability of Band Energy in a Compressively Strained Trilayer MoS2 Sheet
Yeung Yu Hui,Xiaofei Liu,Wenjing Jie,Ngai Yui Chan,Jianhua Hao,Yu-Te Hsu,Lain-Jong Li,Wanlin Guo,Shu Ping Lau +8 more
TL;DR: An electromechanical device that can apply biaxial compressive strain to trilayer MoS2 supported by a piezoelectric substrate and covered by a transparent graphene electrode and reveals the blue-shift of the direct band gap and a higher tunability of the indirect band gap than the direct one.
Journal ArticleDOI
Top–down fabrication of sub-nanometre semiconducting nanoribbons derived from molybdenum disulfide sheets
Xiaofei Liu,Tao Xu,Xing Wu,Zhuhua Zhang,Jin Yu,Hao Qiu,Jinhua Hong,Chuanhong Jin,Jixue Li,Xinran Wang,Litao Sun,Wanlin Guo +11 more
TL;DR: It is found that robust ultrafine molybdenum-sulfide ribbons with a uniform width of 0.35 nm can be widely formed between holes created in a MoS2 sheet under electron irradiation, and a novel top–down route for controllable fabrication of functional building blocks for sub-nanometre electronics is shown.
Journal ArticleDOI
Two-Dimensional Tetragonal TiC Monolayer Sheet and Nanoribbons
TL;DR: The TiC sheet exhibits a novel zigzag-shaped buckling structure with all atoms being quasiplanar tetracoordinate, as favored by strong in-plane C2p-Ti3d bonding and synergetic out-of-plane electronic delocalization, thus promising for wide applications in nanoelectronics.
Journal ArticleDOI
Two‐Dimensional Boron Crystals: Structural Stability, Tunable Properties, Fabrications and Applications
Xu Sun,Xiaofei Liu,Jun Yin,Jin Yu,Yao Li,Yang Hang,Xiaocheng Zhou,Maolin Yu,Jidong Li,Guoan Tai,Wanlin Guo +10 more
TL;DR: A survey of the latest achievements on 2D boron structures, starting from a concise introduction of the bulk allotropes of BORON, borone clusters, and especially potential building blocks for 2D 2D crystals can be found in this paper.
Journal ArticleDOI
Probing van der Waals interactions at two-dimensional heterointerfaces.
TL;DR: MoS2 is shown to exhibit a stronger vdW interaction with graphite than with hexagon boron nitride, which is well described by Lifshitz theory and utilized to construct 2D heterostructures in a sophisticated way.
