Electron-Phonon Scattering in the Presence of Soft Modes and Electron Mobility in SrTiO${}_3$ Perovskite from First Principles

Jin-Jian Zhou, Olle Hellman, Marco Bernardi

Structural phase transitions and soft phonon modes pose a longstanding challenge to computing electron-phonon (e-ph) interactions in strongly anharmonic crystals. Here we develop a…
