Determination of the crystal field splitting energy in Cd3As2 using magnetooptics
G. Krizman, T. Schumann, S. Tchoumakov +4
Symmetry considerations are of extreme importance to the topological properties of crystals. A crystal field splitting δ yields Dirac nodes near the Brillouin zone center in Cd3As2…
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…
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…
Barrier breakdown in a multiple quantum well structure
A. Gomez, V. Berger, N. Pere-Laperne +1
We explore a regime of unipolar electronic transport in a multiple quantum well structure with very large current discontinuities - up to five orders of magnitude. Magneto-transpor…
