Rectification effects in coherent transport through single molecules
arXiv:cond-mat/0611436 · doi:10.1016/j.susc.2007.04.083
Abstract
A minimal model for coherent transport through a donor/acceptor molecular junction is presented. The two donor and acceptor sites are described by single levels energetically separated by an intramolecular tunnel barrier. In the limit of strong coupling to the electrodes a current rectification for different bias voltage polarities occurs. Contacts with recent experiments of molecular rectification are also given.
