Journal ArticleDOI
Structural phase transition in monolayer MoTe 2 driven by electrostatic doping
Ying Wang,Jun Xiao,Hanyu Zhu,Yao Li,Yousif Alsaid,King Y. Fong,Yao Zhou,Siqi Wang,Wu Shi,Wu Shi,Yuan Wang,Alex Zettl,Alex Zettl,Evan J. Reed,Xiang Zhang,Xiang Zhang,Xiang Zhang +16 more
TL;DR: The experimental demonstration of an electrostatic-doping-driven phase transition between the hexagonal and monoclinic phases of monolayer molybdenum ditelluride (MoTe2), which opens up new possibilities for developing phase-change devices based on atomically thin membranes.
Journal ArticleDOI
Large-scale chemical assembly of atomically thin transistors and circuits
Mervin Zhao,Yu Ye,Yu Ye,Yimo Han,Yang Xia,Hanyu Zhu,Siqi Wang,Yuan Wang,David A. Muller,Xiang Zhang,Xiang Zhang,Xiang Zhang +11 more
TL;DR: This work reports on the large-scale, spatially controlled synthesis of heterostructures made of single-layer semiconducting molybdenum disulfide contacting conductive graphene and demonstrates that such chemically assembled atomic transistors exhibit high transconductance, on-off ratio and mobility.
Journal ArticleDOI
Berry curvature memory through electrically driven stacking transitions
Jun Xiao,Jun Xiao,Ying Wang,Hua Wang,Chaitanya Das Pemmaraju,Siqi Wang,Philipp Muscher,Edbert J. Sie,Edbert J. Sie,Clara Nyby,Thomas P. Devereaux,Thomas P. Devereaux,Thomas P. Devereaux,Xiaofeng Qian,Xiang Zhang,Xiang Zhang,Aaron M. Lindenberg,Aaron M. Lindenberg +17 more
TL;DR: In this article, an electrically driven stacking transition is applied to design nonvolatile memory based on the Berry curvature in few-layer WTe$_2$, where the interplay of out-of-plane electric fields and electrostatic doping controls in-plane interlayer sliding and creates multiple polar and centrosymmetric stacking orders.
Journal ArticleDOI
Direct observation of Klein tunneling in phononic crystals.
Xue Jiang,Xue Jiang,Chengzhi Shi,Chengzhi Shi,Zhenglu Li,Zhenglu Li,Siqi Wang,Yuan Wang,Sui Yang,Steven G. Louie,Steven G. Louie,Xiang Zhang,Xiang Zhang +12 more
TL;DR: Using a phononic system comprising a periodic array of dielectric pillars, evidence is provided for the direct observation of Klein tunneling in phononic crystals that could find applications in signal processing, supercollimated beams, and communications.
Journal ArticleDOI
Observation of Rydberg exciton polaritons and their condensate in a perovskite cavity.
Wei Bao,Xiaoze Liu,Fei Xue,Fei Xue,Fan Zheng,Renjie Tao,Siqi Wang,Yang Xia,Mervin Zhao,Jeongmin Kim,Sui Yang,Quanwei Li,Ying Wang,Yuan Wang,Lin-Wang Wang,Allan H. MacDonald,Xiang Zhang,Xiang Zhang +17 more
TL;DR: In this article, the authors observed the formation of Rydberg exciton polaritons (REPs) in a single crystal CsPbBr3 perovskite cavity without any external fields.
