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…
Guidelines for accurate and efficient calculations of mobilities in two-dimensional materials
Jiaqi Zhou, Samuel Poncé, Jean-Christophe Charlier
Emerging two-dimensional (2D) materials bring unprecedented opportunities for electronic applications. The design of high-performance devices requires an accurate prediction of car…
Electron mobility of SnO2 from first principles
Amanda Wang, Kyle Bushick, Nick Pant +6
The transparent conducting oxide SnO2 is a wide bandgap semiconductor that is easily n-type doped and widely used in various electronic and optoelectronic applications. Experimenta…
Electron-phonon physics from first principles using the EPW code
Hyungjun Lee, Samuel Poncé, Kyle Bushick +13
EPW is an open-source software for calculations of electron-phonon interactions and related materials properties. The code combines density functional perturba…
Temperature Dependence of the Energy Levels of Methylammonium Lead Iodide Perovskite from First Principles
Wissam A. Saidi, Samuel Poncé, Bartomeu Monserrat
Environmental effects and intrinsic energy-loss processes lead to fluctuations in the operational temperature of solar cells, which can profoundly influence their power conversion…
The temperature dependence of electronic eigenenergies in the adiabatic harmonic approximation
Samuel Poncé, Gabriel Antonius, Yannick Gillet +5
The renormalization of electronic eigenenergies due to electron-phonon interactions (temperature dependence and zero-point motion effect) is important in many materials. We address…
