Effect of electron-phonon interaction on the opto-electronic properties of semiconducting nanoparticles*

We report on the impact of electron-phonon coupling on the opto-electronic properties of semiconducting nanoparticles. We used a newly developed first-principle method [1] based on many-body-perturbation-theory, which efficiently combines electron-electron and electron-phonon interaction without explicitly evaluating virtual electronic orbitals. The method is implemented in the WEST code [2]. In particular we discuss carbon-based nanoparticles and chalcogenide nanostructures.
