Spatially resolved elastic strain and lattice rotation at threading dislocations in HgCdTe/CdZnTe epilayers by dark-field X-ray microscopy
C. Yildirim, A. Benhadjira, P. Ballet +5
Threading dislocations (TDs) propagating from a CdZnTe (CZT) substrate into a liquid-phase-epitaxy HgCdTe (MCT) epilayer set the minority-carrier lifeti…
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…
Bilinear magnetoresistance in HgTe topological insulator: opposite signs at opposite interfaces demonstrated by gate control
Yu Fu, Jing Li, Jules Papin +12
Spin-orbit effects appearing in topological insulators (TI) and at Rashba interfaces are currently revolutionizing how we can manipulate spins and have led to several newly discove…
Highly efficient spin-to-charge current conversion at room temperature in strained HgTe surface states
P. Noël, C. Thomas, Y. Fu +7
We report the observation of spin-to-charge current conversion in strained mercury telluride at room temperature, using spin pumping experiments. The conversion rates are found to…
Revealing topological Dirac fermions at the surface of strained HgTe thin films via Quantum Hall transport spectroscopy
C. Thomas, O. Crauste, B. Haas +7
We demonstrate evidences of electronic transport via topological Dirac surface states in a thin film of strained HgTe. At high perpendicular magnetic fields, we show that the elect…
Topological surface states of strained Mercury-Telluride probed by ARPES
Olivier Crauste, Yoshiyuki Ohtsubo, Philippe Ballet +6
The topological surface states of strained HgTe have been measured using high-resolution ARPES measurements. The dispersion of surface states form a Dirac cone, which origin is clo…
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…
