【 摘 要 】

Small lattice polarons driven by strong external electric fields are considered. A time-dependent Schrodinger equation is integrated directly in time domain. The field agitates ions both directly and through modulation of carrier density. It is found that when the field is in resonance with local ion oscillations, the polaron is liberated from its self-induced trap and the tunneling frequency increases exponentially.
