Disorder-induced phase transitions in double HgTe quantum wells
S. S. Krishtopenko, A. V. Ikonnikov, B. Jouault +1
By using the self-consistent Born approximation, we investigate topological phase transitions in double HgTe quantum wells (QWs) induced by the short-range impurities. Following th…
Gate tunable terahertz cyclotron emission from two-dimensional Dirac fermions
B. Benhamou-Bui, C. Consejo, S. S. Krishtopenko +15
Two-dimensional Dirac fermions in HgTe quantum wells close to the topological phase transition can generate significant cyclotron emission that is magnetic field tunable in the Ter…
Terahertz cyclotron emission from two-dimensional Dirac fermions
S. Gebert, C. Consejo, S. S. Krishtopenko +13
Since the emergence of graphene, we have seen several proposals for the realization of Landau lasers tunable over the terahertz frequency range. The hope was that the non-equidista…
Temperature Dependent Zero-Field Splittings in Graphene
C. Bray, K. Maussang, C. Consejo +15
Graphene is a quantum spin Hall insulator with a 45 eV wide non-trivial topological gap induced by the intrinsic spin-orbit coupling. Even though this zero-field spin splitting…
Electrical control of excitons in GaN/(Al,Ga)N quantum wells
R. Aristegui, F. Chiaruttini, B. Jouault +7
A giant built-in electric field in the growth direction makes excitons in wide GaN/(Al, Ga)N quantum wells spatially indirect even in the absence of any external bias. Significant…
Large inverted band-gap in strained three-layer InAs/GaInSb quantum wells
C. Avogadri, S. Gebert, S. S. Krishtopenko +17
Quantum spin Hall insulators (QSHIs) based on HgTe and three-layer InAs/GaSb quantum wells (QWs) have comparable bulk band-gaps of about 10--18~meV. The former however features a b…
