Optimal transition states for polaron hopping transport without supercells
Vasilii Vasilchenko, Matteo Giantomassi, Samuel Poncé +1
Polaron formation localizes charge carriers and drives a crossover from band-like to hopping transport in materials. Hopping dynamics can be obtained from DFT supercell calculation…

Variational first-principles approach to self-trapped polarons
Vasilii Vasilchenko, Matteo Giantomassi, Samuel Poncé +1
The behavior of charge carriers in polar materials is governed by electron-phonon interactions, which affect their mobilities via phonon scattering and may localize carriers into s…
