Lifting of the Landau level degeneracy in graphene devices in a tilted magnetic field

F. Chiappini, S. Wiedmann, K. S. Novoselov +4

We report on transport and capacitance measurements of graphene devices in magnetic fields up to 30 T. In both techniques, we observe the full splitting of Landau levels and we emp…

Quantum oscillations of the topological surface states in low carrier concentration crystals of Bi $_{2 - x}$ Sb $_{x}$ Te $_{3 - y}$ Se $_{y}$

Y. Pan, A. M. Nikitin, D. Wu +8

We report a high-field magnetotransport study on selected low-carrier crystals of the topological insulator Bi $_{2 - x}$ Sb $_{x}$ Te $_{3 - y}$ Se $_{y}$ . Monochromatic Shubnikov - de Haas…

Temperature-driven transition from a semiconductor to a topological insulator

Steffen Wiedmann, Andreas Jost, Cornelius Thienel +6

We report on a temperature-induced transition from a conventional semiconductor to a two-dimensional topological insulator investigated by means of magnetotransport experiments on…
