22 May 2002 | | Journal: | Chem. Phys. Lett. 368, 282 (2003) | | Subject: | Chemical Physics; Mesoscopic Systems and Quantum Hall Effect | physics.chem-ph cond-mat.mes-hall | | Abstract: | We investigate the possibility of optical current control through single molecules which are weakly coupled to leads. A master equation approach for the transport through a molecule is combined with a Floquet theory for the time-dependent molecule. This yields an efficient numerical approach to the evaluation of the current through time-dependent nano-structures in the presence of a finite external voltage. We propose tunable optical current switching in two- and three-terminal molecular electronic devices driven by properly adjusted laser fields, i.e. a novel class of molecular transistors. | | Source: | arXiv, physics/0205060 | | Services: | Forum | Review | PDF | Favorites | |
