This work proposes a new type ofmolecular machine, the single-moleculeelectric revolving door, which utilizes conductance dependence uponmolecular conformation as well as destructive quantum interference.We perform electron transport simulations in the zero-bias limit usingthe Landauer formalism together with density functional theory. Thesimulations show that the open- and closed-door states, accompaniedby significant conductance variation, can be operated by an externalelectric field. The large on–off conductance ratio (∼105) implies that the molecular machine can also serve as aneffective switching device. The simultaneous control and detectionof the door states can function at the nanosecond scale, thereby offeringa new capability for molecular-scale devices. [ABSTRACT FROM AUTHOR] |
