Cui-Zu Chang,Cui-Zu Chang,Jinsong Zhang,Xiao Feng,Xiao Feng,Jie Shen,Zuocheng Zhang,Minghua Guo,Kang Li,Yunbo Ou,Pang Wei,Lili Wang,Zhong Qing Ji,Yang Feng,Shuai-Hua Ji,Xi Chen,Jin-Feng Jia,Xi Dai,Zhong Fang,Shou-Cheng Zhang,Ke He,Yayu Wang,Li Lu,Xucun Ma,Qi-Kun Xue +24 more
TL;DR: The observation of the quantum anomalous Hall (QAH) effect in thin films of chromium-doped (Bi,Sb)2Te3, a magnetic topological insulator shows a plateau in the Hall resistance as a function of the gating voltage without any applied magnetic fields, signifying the achievement of the QAH state.
Journal ArticleDOI
Crossover of the three-dimensional topological insulator Bi 2 Se 3 to the two-dimensional limit
Yi Zhang,Ke He,Cui-Zu Chang,Cui-Zu Chang,Can-Li Song,Lili Wang,Xi Chen,Jin-Feng Jia,Zhong Fang,Xi Dai,Wen-Yu Shan,Shun-Qing Shen,Qian Niu,Xiao-Liang Qi,Shou-Cheng Zhang,Xucun Ma,Qi-Kun Xue +16 more
TL;DR: In this article, a study of the topological insulating Bi2Se3 thin films finds that a gap in these gapless surface states opens up in films below a certain thickness, which suggests that in thicker films, gapless states exist on both upper and lower surfaces.
Journal ArticleDOI
Epitaxial growth of two-dimensional stanene
Fengfeng Zhu,Wei-jiong Chen,Yong Xu,Chunlei Gao,Dandan Guan,Canhua Liu,Dong Qian,Shou-Cheng Zhang,Shou-Cheng Zhang,Jin-Feng Jia +9 more
TL;DR: In this paper, the authors reported the successful fabrication of 2D stanene by molecular beam epitaxy, confirmed by atomic and electronic characterization using scanning tunnelling microscopy and angle-resolved photoemission spectroscopy, in combination with first-principles calculations.

Interface-Induced High-Temperature Superconductivity in Single Unit-Cell FeSe Films on SrTiO3
Qingyan Wang,Qingyan Wang,Zhi Li,Wenhao Zhang,Zuocheng Zhang,Jinsong Zhang,Wei Li,Hao Ding,Yunbo Ou,Peng Deng,Kai Chang,Jing Wen,Can-Li Song,Ke He,Jin-Feng Jia,Shuai-Hua Ji,Yayu Wang,Lili Wang,Xi Chen,Xucun Ma,Qi-Kun Xue +20 more
TL;DR: In this paper, the authors reported high transition temperature superconductivity in one unitcell (UC) thick FeSe films grown on a Se-etched SrTiO3 (001) substrate by molecular beam epitaxy (MBE).
Journal ArticleDOI
Superconductivity above 100 K in single-layer FeSe films on doped SrTiO3
Jian-Feng Ge,Zhi-Long Liu,Canhua Liu,Chun Lei Gao,Dong Qian,Qi-Kun Xue,Ying Liu,Jin-Feng Jia +7 more
TL;DR: FeSe/STO is confirmed as an ideal material for studying high-Tc superconductivity by means of in situ four-point probe electrical transport measurements, and rekindle the long-standing idea that electron pairing at interfaces between two different materials can be tailored to achieve high-temperaturesuperconductivity.
