Atomic resolution mapping of localized phonon modes at grain boundaries
Benedikt Haas, Tara M. Boland, Christian Elsässer +5
Phonon scattering at grain boundaries (GBs) is significant in controlling nanoscale device thermal conductivity. However, GBs could also act as waveguides for selected modes. To me…
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…
Nonpolar m-plane GaN/AlGaN heterostructures with intersubband transitions in the 5 to 10 THz band
C. B. Lim, A. Ajay, C. Bougerol +6
This paper assesses intersubband transitions in the 1 to 10 THz frequency range in nonpolar m-plane GaN/AlGaN multi-quantum-wells deposited on free-standing semi-insulating GaN sub…
