Disorder-induced phase transition in Dirac systems beyond the linear approximation
Sergey S. Krishtopenko, Mauro Antezza, Frédéric Teppe
By using the self-consistent Born approximation, we investigate disorder effect induced by the short-range impurities on the band-gap in two-dimensional Dirac systems with the high…
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…
Temperature-dependent magnetospectroscopy of HgTe quantum wells
A. V. Ikonnikov, S. S. Krishtopenko, O. Drachenko +16
We report on magnetospectroscopy of HgTe quantum wells in magnetic fields up to 45 T in temperature range from 4.2 K up to 185 K. We observe intra- and inter-band transitions from…
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…
