Optimizing the Bi_(2-x)Sb_(x)Te_(3-y)Se_(y) solid solutions to approach the intrinsic topological insulator regime
Zhi Ren, A. A. Taskin, Satoshi Sasaki +2
To optimize the bulk-insulating behavior in the topological insulator materials having the tetradymite structure, we have synthesized and characterized single-crystal samples of Bi…

Observations of two-dimensional quantum oscillations and ambipolar transport in the topological insulator Bi2Se3 achieved by Cd doping
Zhi Ren, A. A. Taskin, Satoshi Sasaki +2
We present a defect-engineering strategy to optimize the transport properties of the topological insulator Bi2Se3 to show a high bulk resistivity and clear quantum oscillations. St…

Berry phase of non-ideal Dirac fermions in topological insulators
A. A. Taskin, Yoichi Ando
A distinguishing feature of Dirac fermions is the Berry phase of associated with their cyclotron motions. Since this Berry phase can be experimentally assessed by analyzing the…
