Large bulk resistivity and surface quantum oscillations in the topological insulator Bi2Te2Se
Zhi Ren, A. A. Taskin, Satoshi Sasaki +2
Topological insulators are predicted to present novel surface transport phenomena, but their experimental studies have been hindered by a metallic bulk conduction that overwhelms t…

Angular-dependent oscillations of the magnetoresistance in Bi_2Se_3 due to the three-dimensional bulk Fermi surface
Kazuma Eto, Zhi Ren, A. A. Taskin +2
We observed pronounced angular-dependent magnetoresistance (MR) oscillations in a high-quality Bi2Se3 single crystal with the carrier density of 5x10^18 cm^-3, which is a topologic…
