摘要：

The competing effects of transfer integral (bandwidth) and local vibronic coupling on space- and time-dependent decay of initially localized electrons in anharmonic chains are investigated. The dynamics of electronic localization, caused by electron-vibrational interaction, and the energy redistribution between the electron and lattice is examined and shown to be changed drastically by the appearance of vibrations, localized by vibronic coupling. We consider effects of dynamical disorder, caused by thermal fluctuations, and find that increase in temperature produces diffuse (incoherent) transfer with the conductivity dropping off with temperature increase, as expected in a metal. © 1994 American Institute of Physics.
