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.
