Opposite impact of thermal expansion and phonon anharmonicity on the phonon-limited resistivity of elemental metals from first principles
Ao Wang, Junwen Yin, Félix Antoine Goudreault +3
Understanding electrical resistivity in metals remains a central challenge in quantifying charge transport at finite temperature. Current first-principles calculations based on the…

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.…
