Probing the magnetic band gap of the ferromagnetic topological insulator MnSbTe
Philipp Küppers, Jannik Zenner, Stefan Wimmer +4
Mn-rich MnSbTe is a ferromagnetic topological insulator with yet the highest Curie temperature T_C = 45-50 K. It exhibits a magnetic gap at the Dirac point of the topologic…
Anomalous behavior of the electronic structure of (BiIn)Se across the quantum-phase transition from topological to trivial insulator
J. Sánchez-Barriga, I. Aguilera, L. V. Yashina +9
Using spin- and angle-resolved spectroscopy and relativistic many-body calculations, we investigate the evolution of the electronic structure of (BiIn)Se bulk s…
Band renormalization of blue phosphorus on Au(111)
E. Golias, M. Krivenkov, A. Varykhalov +2
Most recently, theoretical calculations predicted the stability of a novel two-dimensional phosphorus honeycomb lattice named blue phosphorus. Here, we report on the growth of blue…
Laser-induced persistent photovoltage on the surface of a ternary topological insulator at room temperature
J. Sánchez-Barriga, M. Battiato, E. Golias +4
Using time- and angle-resolved photoemission, we investigate the ultrafast response of excited electrons in the ternary topological insulator (BiSb)Te to fs-i…
Negative longitudinal magnetoresistance from anomalous N=0 Landau level in topological materials
B. A. Assaf, T. Phuphachong, E. Kampert +8
Negative longitudinal magnetoresistance (NLMR) is shown to occur in topological materials in the extreme quantum limit, when a magnetic field is applied parallel to the excitation…
Nonmagnetic band gap at the Dirac point of the magnetic topological insulator (BiMnSe
J. Sánchez-Barriga, A. Varykhalov, G. Springholz +17
Magnetic doping is expected to open a band gap at the Dirac point of topological insulators by breaking time-reversal symmetry and to enable novel topological phases. Epitaxial (Bi…
