Momentum resolved spin dynamics of bulk and surface excited states in the topological insulator
C. Cacho, A. Crepaldi, M. Battiato +16
The prospective of optically inducing a spin polarized current for spintronic devices has generated a vast interest in the out-of-equilibrium electronic and spin structure of topol…
Unusual Shubnikov-de Haas oscillations in BiTeCl
C. Martin, A. V. Suslov, S. Buvaev +5
We report measurements of Shubnikov-de Haas (SdH) oscillations in single crystals of BiTeCl at magnetic fields up to 31 T and at temperatures as low as 0.4 K. Two oscillation frequ…
Optical properties of BiTeBr and BiTeCl
A. Akrap, J. Teyssier, A. Magrez +4
We present a comparative study of the optical properties - reflectance, transmission and optical conductivity - and Raman spectra of two layered bismuth-tellurohalides BiTeBr and B…
Tuning the Fermi level through the Dirac point of giant Rashba semiconductor BiTeI with pressure
D. VanGennep, S. Maiti, D. Graf +5
We report measurements of Shubnikov-de Haas oscillations in the giant Rashba semiconductor BiTeI under applied pressures up to . We observe one high frequency…
