Electron-phonon coupling in the spin-split valence band of single layer WS
Nicki Frank Hinsche, Arlette S. Ngankeu, Kevin Guilloy +15
The absence of inversion symmetry leads to a strong spin-orbit splitting of the upper valence band of semiconducting single layer transition metal dichalchogenides such as MoS…
Quasi one-dimensional metallic band dispersion in the commensurate charge density wave of -TaS
Arlette S. Ngankeu, Kevin Guilloy, Sanjoy K. Mahatha +5
The commensurate charge density wave (CDW) in the layered compound -TaS has hitherto mostly been treated as a quasi two-dimensional phenomenon. Recent band structure calcul…
Optically pumped GeSn micro-disks with 16 % Sn lasing at 3.1 um up to 180K
V. Reboud, A. Gassenq, N. Pauc +13
Recent demonstrations of optically pumped lasers based on GeSn alloys put forward the prospect of efficient laser sources monolithically integrated on a Si photonic platform. For i…
Raman spectral shift versus strain and composition in GeSn layers with: 6 to 15% Sn contents
A. Gassenq, L. Milord, J. Aubin +8
GeSn alloys are the subject of intense research activities as these group IV semiconductors present direct bandgap behaviors for high Sn contents. Today, the control of strain beco…
