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…
Current-induced enhancement of photo-response in graphene THz radiation detectors
K. Indykiewicz, C. Bray, C. Consejo +4
Thermoelectric readout in a graphene THz radiation detector requires a p-n junction across the graphene channel. Even without an intentional p-n junction, two latent junctions can…
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…
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…
Photo-induced plasmon-phonon coupling in PbTe
M. P. Jiang, M. Trigo, S. Fahy +19
We report the observation of photo-induced plasmon-phonon coupled modes in the group IV-VI semiconductor PbTe using Fourier-transform inelastic X-ray scattering at the Linac Cohere…
