Ab initio electron-two-phonon scattering in GaAs from next-to-leading order perturbation theory
Electron-phonon scattering plays a decisive role in electron transport and is taken into account in ab initio calculations by leading-order perturbations involving scattering events with one phonon. Here, the authors show that higher-order effects are comparable in magnitude to the leading order in...

| Sumario: | Electron-phonon scattering plays a decisive role in electron transport and is taken into account in ab initio calculations by leading-order perturbations involving scattering events with one phonon. Here, the authors show that higher-order effects are comparable in magnitude to the leading order in polar semiconductors. |
