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…
Dirac parameters and topological phase diagram of Pb1-xSnxSe from magneto-spectroscopy
G. Krizman, B. A. Assaf, T. Phuphachong +4
Pb1-xSnxSe hosts 3D massive Dirac fermions across the entire composition range for which the crystal structure is cubic. In this work, we present a comprehensive experimental mappi…
Large magnetic gap at the Dirac point in a Mn-induced BiTe heterostructure
E. D. L. Rienks, S. Wimmer, P. S. Mandal +15
Magnetically doped topological insulators enable the quantum anomalous Hall effect (QAHE) which provides quantized edge states for lossless charge transport applications. The edge…
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…
