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.

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
Two-dimensional itinerant ferromagnetism in atomically thin Fe3GeTe2.
Zaiyao Fei,Bevin Huang,Paul Malinowski,Wenbo Wang,Tiancheng Song,Joshua Sanchez,Wang Yao,Di Xiao,Xiaoyang Zhu,Andrew F. May,Weida Wu,David Cobden,Jiun-Haw Chu,Xiaodong Xu +13 more
TL;DR: It is demonstrated that Fe3GeTe2 (FGT), an exfoliable vdW magnet, exhibits robust 2D ferromagnetism with strong perpendicular anisotropy when thinned down to a monolayer.
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.
