Li Wang,Li Wang,Xiaozhi Xu,Leining Zhang,Ruixi Qiao,Muhong Wu,Zhichang Wang,Shuai Zhang,Jing Liang,Zhihong Zhang,Zhibin Zhang,Wang Chen,Xuedong Xie,Junyu Zong,Yuwei Shan,Yi Guo,Marc Georg Willinger,Hui Wu,Qunyang Li,Wenlong Wang,Peng Gao,Shiwei Wu,Yi Zhang,Ying Jiang,Ying Jiang,Dapeng Yu,Enge Wang,Xuedong Bai,Zhu-Jun Wang,Feng Ding,Kaihui Liu +30 more
TL;DR: The epitaxial growth of large single-crystal hexagonal boron nitride monolayers on low-symmetry copper foils is demonstrated and is expected to facilitate the wide application of 2D devices and lead to the epitaxials growth of broad non-centrosymmetric 2D materials, such as various transition-metal dichalcogenides20–23, to produce large single crystals.

Giant and nonreciprocal second harmonic generation from layered antiferromagnetism in bilayer CrI3
Zeyuan Sun,Yangfan Yi,Tiancheng Song,Genevieve Clark,Bevin Huang,Yuwei Shan,Shuang Wu,Di Huang,Gao Chunlei,Zhanghai Chen,Michael McGuire,Ting Cao,Di Xiao,Wei-Tao Liu,Wang Yao,Xiaodong Xu,Shiwei Wu +16 more
TL;DR: Large second-harmonic generation is observed in antiferromagnetic bilayers of CrI3, providing information about the microscopic origin of layered antiferROMagnetism and motivating the use of two-dimensional magnets in nonlinear optical devices.

Journal ArticleDOI
Gate-tunable third-order nonlinear optical response of massless Dirac fermions in graphene
Tao Jiang,Di Huang,Jinluo Cheng,Xiaodong Fan,Zhihong Zhang,Yuwei Shan,Yangfan Yi,Yunyun Dai,Lei Shi,Kaihui Liu,Changgan Zeng,Jian Zi,John E. Sipe,Y. R. Shen,Y. R. Shen,Wei-Tao Liu,Shiwei Wu +16 more
TL;DR: In this paper, an experimental study of third-order optical nonlinearity of Graphene was conducted using gate tuning to adjust the doping level and vary the resonant condition.
Journal ArticleDOI
Kinetic Nature of Grain Boundary Formation in As-Grown MoS2 Monolayers
Jingxin Cheng,Tao Jiang,Qingqing Ji,Yu Zhang,Zhiming Li,Yuwei Shan,Yanfeng Zhang,Xingao Gong,Wei-Tao Liu,Shiwei Wu +9 more
TL;DR: Grain boundaries in as-grown polycrystalline MoS2 monolayers are revealed by second-harmonic-generation microscopy through the anisotropic polarization pattern and phase interference at the grain boundary, grain edge termination and boundary types are identified.
