Self-consistent electron lifetimes for electron-phonon scattering
Jae-Mo Lihm, Samuel Poncé, Cheol-Hwan Park
Acoustic phonons in piezoelectric materials strongly couple to electrons through a macroscopic electric field. We show that this coupling leads to a momentum-dependent divergence o…

Enhanced Spin Hall Ratio in Two-Dimensional Semiconductors
Jiaqi Zhou, Samuel Poncé, Jean-Christophe Charlier
The conversion efficiency from charge current to spin current via spin Hall effect is evaluated by the spin Hall ratio (SHR). Through state-of-the-art calculations invo…
