Landau level spectroscopy of BiTe
I. Mohelsky, A. Dubroka, J. Wyzula +9
Here we report on Landau level spectroscopy in magnetic fields up to 34 T performed on a thin film of topological insulator BiTe epitaxially grown on a BaF substrate. T…
Avoided level crossing at the magnetic field induced topological phase transition due to spin-orbital mixing
G. Krizman, B. A. Assaf, M. Orlita +7
In 3D topological insulators, an effective closure of the bulk energy gap with increasing magnetic field expected at a critical point can yield a band crossing at a gapless Dirac n…
Tunable Dirac interface states in topological superlattices
G. Krizman, B. A. Assaf, T. Phuphachong +6
Relativistic Dirac fermions are ubiquitous in condensed matter physics. Their mass is proportional to the material energy gap and the ability to control and tune the mass has becom…
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…
Photoemission of BiSe with Circularly Polarized Light: Probe of Spin Polarization or Means for Spin Manipulation?
J. Sánchez-Barriga, A. Varykhalov, J. Braun +12
Topological insulators are characterized by Dirac cone surface states with electron spins aligned in the surface plane and perpendicular to their momenta. Recent theoretical and ex…
