Journal ArticleDOI
Development of a vacuum ultraviolet laser-based angle-resolved photoemission system with a superhigh energy resolution better than 1 meV.
Guodong Liu,Guiling Wang,Yong Zhu,Hongbo Zhang,Guochun Zhang,Xiaoyang Wang,Yong Zhou,Wentao Zhang,Haiyun Liu,Lin Zhao,Jianqiao Meng,Xiaoli Dong,Chuangtian Chen,Zuyan Xu,Xingjiang Zhou +14 more
TL;DR: The new VUV laser-based ARPES system exhibits superior performance, including superhigh energy resolution better than 1 meV, high momentum resolution, superhigh photon flux, and much enhanced bulk sensitivity, which are demonstrated from measurements on a typical Bi2Sr2CaCu2O8 high temperature superconductor.
Journal ArticleDOI
Distinct fermi surface topology and nodeless superconducting gap in a (Tl0.58Rb0.42)Fe1.72Se2 superconductor.
Daixiang Mou,Shanyu Liu,Xiaowen Jia,Junfeng He,Yingying Peng,Lin Zhao,Li Yu,Guodong Liu,Shaolong He,Xiaoli Dong,Jun Zhang,Hangdong Wang,Chiheng Dong,Minghu Fang,Xiaoyang Wang,Qinjun Peng,Zhimin Wang,Shenjin Zhang,Feng Yang,Zuyan Xu,Chuangtian Chen,X. J. Zhou +21 more
TL;DR: The observed new Fermi surface topology and its associated superconducting gap will provide key insights and constraints into the understanding of the superconductivity mechanism in iron-based superconductors.
Journal ArticleDOI
Evidence of Topological Surface State in Three-Dimensional Dirac Semimetal Cd3As2
Hemian Yi,Zhijun Wang,Chaoyu Chen,Youguo Shi,Ya Feng,Aiji Liang,Zhuojin Xie,Shaolong He,Junfeng He,Yingying Peng,Xu Liu,Yan Liu,Lin Zhao,Guodong Liu,Xiaoli Dong,Jun Zhang,Masashi Nakatake,Masashi Arita,Kenya Shimada,Hirofumi Namatame,Masaki Taniguchi,Zuyan Xu,Chuangtian Chen,Xi Dai,Zhong Fang,Xingjiang Zhou +25 more
TL;DR: The electronic structure of Cd3As2 is investigated by angle-resolved photoemission measurements on the crystal surface and detailed band structure calculations and the topological surface state with a linear dispersion approaching the Fermi level is identified for the first time.
Journal ArticleDOI
Common electronic origin of superconductivity in (Li,Fe)OHFeSe bulk superconductor and single-layer FeSe/SrTiO 3 films
Lin Zhao,Aiji Liang,Dongna Yuan,Yong Hu,Defa Liu,Jianwei Huang,Shaolong He,Bing Shen,Yu Xu,Xu Liu,Li Yu,Guodong Liu,Huaxue Zhou,Yulong Huang,Xiaoli Dong,Fang Zhou,Kai Liu,Zhong-Yi Lu,Zhongxian Zhao,Chuangtian Chen,Zuyan Xu,Xingjiang Zhou +21 more
TL;DR: It is found that this single-phase bulk superconductor shows remarkably similar electronic behaviours to that of the superconducting single-layer FeSe/SrTiO3 films in terms of Fermi surface topology, band structure and the gap symmetry.
Journal ArticleDOI
Robustness of topological order and formation of quantum well states in topological insulators exposed to ambient environment
Chaoyu Chen,Shaolong He,Hongming Weng,Wentao Zhang,Lin Zhao,Haiyun Liu,Xiaowen Jia,Daixiang Mou,Shanyu Liu,Junfeng He,Yingying Peng,Ya Feng,Zhuojin Xie,Guodong Liu,Xiaoli Dong,Jun Zhang,Xiaoyang Wang,Qinjun Peng,Zhimin Wang,Shenjin Zhang,Feng Yang,Chuangtian Chen,Zuyan Xu,Xi Dai,Zhong Fang,Xingjiang Zhou +25 more
TL;DR: High resolution angle-resolved photoemission measurements are reported to directly probe the surface state of the prototypical topological insulators, Bi2Se3 and Bi2Te3, upon exposing to various environments and find that the topological order is robust even when the surface is exposed to air at room temperature.
