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-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…
