Superconductivity in CuxBi2Se3 and its implications for pairing in the undoped topological insulator
Y. S. Hor, A. J. Williams, J. G. Checkelsky +7
Bi2Se3 is one of a handful of known topological insulators. Here we show that copper intercalation in the van der Waals gaps between the Bi2Se3 layers, yielding an electron concent…
Topological Surface States Protected From Backscattering by Chiral Spin Texture
Pedram Roushan, Jungpil Seo, Colin V. Parker +7
Topological insulators are a new class of insulators in which a bulk gap for electronic excitations is generated by strong spin orbit coupling. These novel materials are distinguis…
p-type Bi2Se3 for topological insulator and low temperature thermoelectric applications
Y. S. Hor, A. Richardella, P. Roushan +6
The growth and elementary properties of p-type Bi2Se3 single crystals are reported. Based on a hypothesis about the defect chemistry of Bi2Se3, the p-type behavior has been induced…
