Polarons in two-dimensional atomic crystals
Weng Hong Sio, Feliciano Giustino
The polaron is the archetypal example of a quasiparticle emerging from the interaction between fermionic and bosonic fields in quantum field theory. In crystalline solids, polarons…
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…
Anharmonic electron-phonon coupling in ultrasoft and locally disordered perovskites
Marios Zacharias, George Volonakis, Feliciano Giustino +1
Anharmonicity and local disorder (polymorphism) are ubiquitous in perovskite physics, inducing various phenomena observed in scattering and spectroscopy experiments. Several of the…
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…
