Many-particle hybridization of optical transitions from zero-mode Landau levels in HgTe quantum wells
S. Ruffenach, S. S. Krishtopenko, A. V. Ikonnikov +6
We present far-infrared magnetospectroscopy measurements of a HgTe quantum well in the inverted band structure regime over the temperature range of 2 to 60 K. The particularly low…
Nonlinear Terahertz Electroluminescence from Dirac Landau Polaritons
B. Benhamou-Bui, C. Consejo, S. S. Krishtopenko +15
We report Dirac Landau polaritons observed by terahertz (THz) magnetoreflectivity spectroscopy, demonstrating strong coupling between cyclotron transitions of two-dimensional (2D)…
Selective area epitaxy of in-plane HgTe nanostrcutures on CdTe(001) substrate
Nicolas Chaize, Xavier Baudry, Pierre-Henri Jouneau +10
Semiconductor nanowires are believed to play a crucial role for future applications in electronics, spintronics and quantum technologies. A potential candidate is HgTe but its sens…
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…
Strained HgTe: a textbook 3D topological insulator
Clément Bouvier, Tristan Meunier, Philippe Ballet +3
Topological insulators can be seen as band-insulators with a conducting surface. The surface carriers are Dirac particles with an energy which increases linearly with momentum. Thi…
