Transport evidence of surface states in magnetic topological insulator MnBi2Te4
Michael Wissmann, Romain Giraud, Börge Mehlhorn +8
Magnetic topological insulators can host chiral 1D edge channels at zero magnetic field, when a magnetic gap opens at the Dirac point in the band structure of 2D topological surfac…
Electrostatic gate-controlled quantum interference in a high-mobility two-dimensional electron gas at the (LaSr)(AlTa)O/SrTiO interface
Km Rubi, Kun Han, Huang Zhen +4
We report quantum oscillations in magnetoresistance that are periodic in magnetic field (), observed at the interface between (LaSr)(AlTa)O…
Unconventional quantum oscillations and evidence of nonparabolic electronic states in quasi-two-dimensional electron system at complex oxide interfaces
Km Rubi, Denis R. Candido, Manish Dumen +10
The simultaneous occurrence of electric-field controlled superconductivity and spin-orbit interaction makes two-dimensional electron systems (2DES) constructed from perovskite tran…
Electrical Properties and Subband Occupancy at the (La,Sr)(Al,Ta)O/SrTiO Interface
K. Han, Z. Huang, S. W. Zeng +9
The quasi two-dimensional electron gas (q-2DEG) at oxide interfaces provides a platform for investigating quantum phenomena in strongly correlated electronic systems. Here, we stud…
Puddle-induced resistance oscillations in the breakdown of the graphene quantum Hall effect
M. Yang, O. Couturaud, W. Desrat +11
We report on the stability of the quantum Hall plateau in wide Hall bars made from a chemically gated graphene film grown on SiC. The quantized plateau appears from fields $B…
Integer Quantum Hall Effect in Trilayer Graphene
A. Kumar, W. Escoffier, J. M. Poumirol +7
The Integer Quantum Hall Effect (IQHE) is a distinctive phase of two-dimensional electronic systems subjected to a perpendicular magnetic field. Thus far, the IQHE has been observe…
Electron-hole coexistence in disordered graphene probed by high-field magneto-transport
J. M. Poumirol, W. Escoffier, A. Kumar +3
We report on magneto-transport measurement in disordered graphene under pulsed magnetic field of up to 57T. For large electron or hole doping, the system displays the expected anom…
Possible Fractional Quantum Hall Effect in Graphite
Y. Kopelevich, B. Raquet, M. Goiran +6
Measurements of basal plane longitudinal rho_b(B) and Hall rho_H(B) resistivities were performed on highly oriented pyrolytic graphite (HOPG) samples in pulsed magnetic field up to…
