Carrier mobilities and electron-phonon interactions beyond DFT
Aleksandr Poliukhin, Nicola Colonna, Francesco Libbi +2
Electron-phonon coupling is a key interaction that governs diverse physical processes such as carrier transport, superconductivity, and optical absorption. Calculating such interac…
Extraction of the self energy and Eliashberg function from angle resolved photoemission spectroscopy using the xARPES code
Thomas P. van Waas, Christophe Berthod, Jan Berges +3
Angle-resolved photoemission spectroscopy is a powerful experimental technique for studying anisotropic many-body interactions through the electron spectral function. Existing atte…
Importance of Non-Adiabatic Effects on Kohn Anomalies in 1D metals
Enrico Marazzi, Samuel Poncé, Jean-Christophe Charlier +1
Kohn anomalies are kinks or dips in phonon dispersions which are pronounced in low-dimensional materials. We investigate the effects of non-adiabatic phonon self-energy on Kohn ano…
Beyond-quasiparticle transport with vertex correction: self-consistent ladder formalism for electron-phonon interactions
Jae-Mo Lihm, Samuel Poncé
We present a self-consistent many-body framework for computing phonon-limited electronic transport from first principles, incorporating both beyond-quasiparticle effects and vertex…
Impact of anharmonicity on the carrier mobility of the Pb-free CsSnBr perovskite
Junwen Yin, Olle Hellman, Samuel Poncé
Charge carrier mobilities are critical parameters in halide perovskite solar cells, governing their average carrier velocity under an applied electric field and overall efficiency.…
Phonon-limited carrier transport in the Weyl semimetal TaAs
Zhe Liu, Shashi B. Mishra, Jae-Mo Lihm +2
Topological Weyl semimetals represent a novel class of quantum materials that exhibit remarkable properties arising from their unique electronic structure. In this work, we employ…
