Resolving spin currents and spin densities generated by charge-spin interconversion in systems with reduced crystal symmetry
Lorenzo Camosi, Josef Svetlik, Marius V. Costache +7
The ability to control the generation of spins in arbitrary directions is a long-sought goal in spintronics. Charge-to-spin interconversion (CSI) phenomena depend strongly on symme…
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…
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…
Shubnikov-de Haas oscillations from topological surface states of metallic BiSeTe
Keshav Shrestha, Vera Marinova, Bernd Lorenz +1
We have studied the quantum oscillations in the conductivity of metallic, p-type BiSeTe. The dependence of the oscillations on the angle of the magnetic field w…
Fingerprints of Inelastic Transport at the Surface of the Topological Insulator Bi2Se3: Role of Electron-Phonon Coupling
M. V. Costache, I. Neumann, J. F. Sierra +4
We report on electric-field and temperature dependent transport measurements in exfoliated thin crystals of BiSe topological insulator. At low temperatures ( K) a…
