摘要: We study the electronic transport through a single-molecule transistor (SMT) by considering the phonon-associated tunneling rate We find that the electron-phonon interaction (EPI) changes the constant conductivities of the leads into a multi-channel structure of single vibration frequency This interference of the multi-channel tunneling process results in a bias-dependent tunneling rate and obscures the conductance peaks at large bias voltage The bias-dependent tunneling rate further causes a remarkable conductivity gap between the chemical potential of the leads (n = 0) and the first phonon sideband (n = 1) These anomalies are consistent with the experimental observations in transport experiments (C) 2010 Elsevier Ltd All rights reserved
