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.
