Experimental Demonstration of Topological Surface States Protected by Time-Reversal Symmetry
Tong Zhang,Tong Zhang,Peng Cheng,Xi Chen,Jin-Feng Jia,Xucun Ma,Ke He,Lili Wang,Haijun Zhang,Xi Dai,Zhong Fang,Xincheng Xie,Qi-Kun Xue,Qi-Kun Xue +13 more
TL;DR: By studying the voltage-dependent standing wave patterns, the energy dispersion E(k) is determined, which confirms the Dirac cone structure of the topological states, and shows that, very different from the conventional surface states, backscattering of theTopological states by nonmagnetic impurities is completely suppressed.
Journal ArticleDOI
Intrinsic Topological Insulator Bi2Te3 Thin Films on Si and Their Thickness Limit
Yaoyi Li,Guang Wang,Xie-Gang Zhu,Minhao Liu,Cun Ye,Xi Chen,Yayu Wang,Ke He,Lili Wang,Xucun Ma,Haijun Zhang,Xi Dai,Zhong Fang,Xincheng Xie,Ying Liu,Xiao-Liang Qi,Jin-Feng Jia,Shou-Cheng Zhang,Qi-Kun Xue,Qi-Kun Xue +19 more
TL;DR: In situ angle-resolved photo-emission spectroscopy measurement reveals that the as-grown Bi2Te3 films are intrinsic topological insulators and the single-Dirac-cone surface state develops at a thickness of two quintuple layers.

Landau Quantization of Topological Surface States in Bi2Se3
Peng Cheng,Can-Li Song,Tong Zhang,Tong Zhang,Yanyi Zhang,Yilin Wang,Jin-Feng Jia,Jing Wang,Yayu Wang,Bang-Fen Zhu,Xi Chen,Xucun Ma,Ke He,Lili Wang,Xi Dai,Zhong Fang,Xincheng Xie,Xiao-Liang Qi,Xiao-Liang Qi,Chao-Xing Liu,Chao-Xing Liu,Shou-Cheng Zhang,Qi-Kun Xue,Qi-Kun Xue +23 more
TL;DR: The zeroth Landau level is discovered, predicted to give rise to the half-quantized Hall effect for the topological surface states, which may eventually lead to the realization of quantum Hall effect in topological insulators.

Site-specific kondo effect at ambient temperatures in iron-based molecules
Li Gao,Wei Ji,Yibin Hu,Zhihai Cheng,Zongwu Deng,Qing Huo Liu,Nan Jiang,Xiao Lin,Wei Guo,Shixuan Du,Werner A. Hofer,Xincheng Xie,Xincheng Xie,Hong-Jun Gao +13 more
TL;DR: It is shown that for iron phthalocyanine a Kondo temperature in spectroscopic measurements which is well above room temperature is found, and that the signal of the resonance depends strongly on the adsorption site of the molecule on a gold surface.
Journal ArticleDOI
Numerical study of the topological Anderson insulator in HgTe/CdTe quantum wells
TL;DR: In this article, the disorder effect on the transport properties in the HgTe/CdTe semiconductor quantum wells was studied and it was shown that at moderate disorder strength, the initially unquantized two-terminal conductance becomes quantized and the system makes a transition to the topological Anderson insulator (TAI).
