Weak antilocalization effect due to topological surface states in BiSeTe

K. Shrestha, D. Graf, V. Marinova +2

We have investigated the weak antilocalization (WAL) effect in the p-type BiSeTe topological system. The magnetoconductance shows a cusp-like feature at low mag…

Extremely large non-saturating magnetoresistance and ultrahigh mobility due to topological surface states in metallic Bi2Te3 topological insulator

K. Shrestha, M. Chou, D. Graf +3

Weak antilocalization (WAL) effects in Bi2Te3 single crystals have been investigated at high and low bulk charge carrier concentrations. At low charge carrier density the WAL curve…

Large magnetoresistance and Fermi surface study of SbSeTe single crystal

K. Shrestha, V. Marinova, D. Graf +2

We have studied the magnetotransport properties of a SbSeTe single crystal. Magnetoresistance (MR) is maximum when the magnetic field is perpendicular to the sample surface…

Simultaneous detection of quantum oscillations from bulk and topological surface states in metallic Bi2Se2.1Te0.9

Keshav Shrestha, David E. Graf, Vera Marinova +2

Shubnikov-de Haas (SdH) oscillations in metallic Bi2Se2.1Te0.9 are studied in magnetic fields up to 35 Tesla. It is demonstrated that two characteristic frequencies determine the q…

Quantum oscillations in metallic Sb2Te2Se topological insulator

K. Shrestha, V. Marinova, D. Graf +2

We have studied the magnetotransport properties of the metallic, p-type Sb2Te2Se which is a topological insulator. Magnetoresistance shows Shubnikov de Haas oscillations in fields…
