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…
Effect of dynamical screening in the Bethe-Salpeter framework: Excitons in crystalline naphthalene
Xiao Zhang, Joshua A. Leveillee, André Schleife
Solving the Bethe-Salpeter equation (BSE) for the optical polarization functions is a first principles means to model optical properties of materials including excitonic effects. O…
Phonon-assisted optical absorption of SiC polytypes from first principles
Xiao Zhang, Emmanouil Kioupakis
Silicon carbide (SiC) is an indirect-gap semiconductor material widely used in electronic and optoelectronic applications. While experimental measurements of the phonon-assisted ab…
Ab initio calculation of carrier mobility in semiconductors including ionized-impurity scattering
Joshua Leveillee, Xiao Zhang, Emmanouil Kioupakis +1
The past decade has seen the emergence of ab initio computational methods for calculating phonon-limited carrier mobilities in semiconductors with predictive accuracy. More realist…
