Journal ArticleDOI
Experimental realization of a three-dimensional topological insulator, Bi2Te3
Yulin Chen,James Analytis,James Analytis,Jiun-Haw Chu,Jiun-Haw Chu,Zhongkai Liu,Zhongkai Liu,Sung-Kwan Mo,Sung-Kwan Mo,Xiao-Liang Qi,Xiao-Liang Qi,Huaiying Zhang,Donghui Lu,Xi Dai,Zhong Fang,Shou-Cheng Zhang,Shou-Cheng Zhang,Ian R. Fisher,Ian R. Fisher,Zahid Hussain,Zhi-Xun Shen,Zhi-Xun Shen +21 more
TL;DR: The results establish that Bi2Te3 is a simple model system for the three-dimensional topological insulator with a single Dirac cone on the surface, and points to promising potential for high-temperature spintronics applications.
Journal ArticleDOI
Massive Dirac Fermion on the Surface of a Magnetically Doped Topological Insulator
Yulin Chen,Jiun-Haw Chu,Jiun-Haw Chu,James Analytis,James Analytis,Zhongkai Liu,Zhongkai Liu,Kyushiro Igarashi,Hsueh-Hui Kuo,Hsueh-Hui Kuo,Xiao-Liang Qi,Xiao-Liang Qi,Sung-Kwan Mo,Robert G. Moore,Donghui Lu,Makoto Hashimoto,Makoto Hashimoto,Takao Sasagawa,Shou-Cheng Zhang,Shou-Cheng Zhang,Ian R. Fisher,Ian R. Fisher,Zahid Hussain,Zhi-Xun Shen,Zhi-Xun Shen +24 more
TL;DR: In this article, the authors introduced magnetic dopants into the three-dimensional topological insulator dibismuth triselenide (Bi2Se3) to break the time reversal symmetry and further position the Fermi energy inside the gaps by simultaneous magnetic and charge doping.
Journal ArticleDOI
In-plane resistivity anisotropy in an underdoped iron arsenide superconductor.
Jiun-Haw Chu,Jiun-Haw Chu,James Analytis,James Analytis,Kristiaan De Greve,Peter L. McMahon,Zahirul Islam,Yoshihisa Yamamoto,Yoshihisa Yamamoto,Ian R. Fisher,Ian R. Fisher +10 more
TL;DR: It is revealed that the representative iron arsenide Ba(Fe1−xCox)2As2 develops a large electronic anisotropy at this transition via measurements of the in-plane resistivity of detwinned single crystals, with the resistivity along the shorter b axis ρb being greater than ρa.
Journal ArticleDOI
Two-dimensional surface state in the quantum limit of a topological insulator
James Analytis,James Analytis,Ross D. McDonald,Scott Riggs,Jiun-Haw Chu,Jiun-Haw Chu,Gregory S. Boebinger,Ian R. Fisher,Ian R. Fisher +8 more
TL;DR: For an ideal topological insulator, the metallic surface states should be easy to measure using transport techniques; however, the bulk is not completely insulating as mentioned in this paper, and improving the "leaky" bulk state proves crucial for measuring the surface Dirac fermions, including correlation effects.
Journal ArticleDOI
Divergent Nematic Susceptibility in an Iron Arsenide Superconductor
Jiun-Haw Chu,Jiun-Haw Chu,Hsueh-Hui Kuo,Hsueh-Hui Kuo,James Analytis,James Analytis,Ian R. Fisher,Ian R. Fisher +7 more
TL;DR: In this paper, the authors show how measurement of the divergent nematic susceptibility of the iron pnictide superconductor Ba(Fe(1-x)Co(x))(2)As (2) distinguishes an electronic nematic phase transition from a simple ferroelastic distortion.
