Realistic picture of helical edge states in HgTe quantum wells
S. S. Krishtopenko, F. Teppe
We propose a minimal effective two-dimensional Hamiltonian for HgTe/CdHgTe quantum wells (QWs) describing the side maxima of the first valence subband. By using the Hamiltonian, we…

Large gap quantum spin Hall insulator, massless Dirac fermions and bilayer graphene analogue in InAs/Ga(In)Sb heterostructures
S. S. Krishtopenko, F. Teppe
The quantum spin Hall insulator (QSHI) state has been demonstrated in two semiconductor systems - HgTe/CdTe quantum wells (QWs) and InAs/GaSb QW bilayers. Unlike the HgTe/CdTe QWs,…

Temperature-induced topological phase transition in HgTe quantum wells
A. M. Kadykov, S. S. Krishtopenko, B. Jouault +9
We report a direct observation of temperature-induced topological phase transition between trivial and topological insulator in HgTe quantum well. By using a gated Hall bar device,…
