Journal ArticleDOI
Tuning Local Electrical Conductivity via Fine Atomic Scale Structures of Two-Dimensional Interfaces.
Shuai Zhang,Lei Gao,Aisheng Song,Xiaohu Zheng,Quanzhou Yao,Tianbao Ma,Zengfeng Di,Xi-Qiao Feng,Qunyang Li +8 more
TL;DR: Using conductive atomic force microscopy (c-AFM), for the first time, this work directly confirms the conjecture that the electrical conductivity of physisorbed 2D material-metal/semiconductor interfaces is determined by the local electronic charge transfer and demonstrates that the electronic chargeTransfer can be fine-tuned by the topological defects of 2D materials and the atomic stacking with respect to the substrate.
Journal ArticleDOI
Modeling Atomic-Scale Electrical Contact Quality Across Two-Dimensional Interfaces.
Aisheng Song,Ruoyu Shi,Hongliang Lu,Lei Gao,Qunyang Li,Hui Guo,Yanmin Liu,Jie Zhang,Yuan Ma,Xin Tang,Shixuan Du,Xin Li,Xiao Liu,Yuanzhong Hu,Hong-Jun Gao,Jianbin Luo,Tianbao Ma +16 more
TL;DR: This real-space model unravels the atomic-level spatial modulation of contact conductance, and the twist angle-dependent interlayer conductance between misoriented graphene layers, through atomically resolved conductive atomic force microscopy.
Journal ArticleDOI
Oxide-assisted growth of scalable single-crystalline graphene with seamlessly stitched millimeter-sized domains on commercial copper foils
Yang Wang,Yu Cheng,Yunlu Wang,Shuai Zhang,Xuewei Zhang,Shaoqian Yin,Miao Wang,Yang Xia,Qunyang Li,Pei Zhao,Hongtao Wang +10 more
TL;DR: In this article, the authors presented the CVD growth of scalable single-crystalline graphene by seamless stitching millimeter-sized unidirectional aligned hexagonal domains using different types of commercial Cu foils without repeated substrate polishing and H2-annealing processes.
Journal ArticleDOI
Lateral force modulation by moiré superlattice structure: Surfing on periodically undulated graphene sheets
TL;DR: In this paper, the authors used molecular dynamics simulations to reveal that a periodic offset modulation in lateral force is produced when a tip slides over graphene with varying height, due to geometric undulation of graphene due to its different stacking states on the substrate.
Journal ArticleDOI
Synergistic adhesion mechanisms of spider capture silk
Yang Guo,Zheng Chang,Hao-Yuan Guo,Wei Fang,Qunyang Li,Hong-Ping Zhao,Xi-Qiao Feng,Huajian Gao +7 more
TL;DR: A synergistic enhancement mechanism due to the elasticity of silk fibres is revealed, deepening the understanding of the working principles of spider silk and suggesting guidelines for biomimetic designs of spider-inspired adhesion and capture devices.
