Massless Dirac fermions in III-V semiconductor quantum wells
S. S. Krishtopenko, W. Desrat, K. E. Spirin +12
We report on the clear evidence of massless Dirac fermions in two-dimensional system based on III-V semiconductors. Using a gated Hall bar made on a three-layer InAs/GaSb/InAs quan…
Temperature-driven single-valley Dirac fermions in HgTe quantum wells
M. Marcinkiewicz, S. Ruffenach, S. S. Krishtopenko +13
We report on temperature-dependent magnetospectroscopy of two HgTe/CdHgTe quantum wells below and above the critical well thickness . Our results, obtained in magnetic fields…
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…
Magneto-optical signature of massless Kane electrons in Cd3As2
A. Akrap, M. Hakl, S. Tchoumakov +21
We report on optical reflectivity experiments performed on Cd3As2 over a broad range of photon energies and magnetic fields. The observed response clearly indicates the presence of…
Temperature-driven massless Kane fermions in HgCdTe crystals: verification of universal velocity and rest-mass description
F. Teppe, M. Marcinkiewicz, S. S. Krishtopenko +15
It has recently been shown that the electronic states in bulk gapless HgCdTe offer another realization of pseudo-relativistic three-dimensional particles in a condensed matter syst…
