Current-Driven Oscillations and Time-Dependent Transport in Nanojunctions

Resonance inelastic conduction in molecular-scale electronics can be used to channel energy into a given mode of the molecular component to generate a desired motion. Dependence of the conductance properties on the molecular configuration, in turn, leads to a time-modulated current whose temporal properties are subject to control. We use an ab initio nonequilibrium formalism and the example of Au-C60-Au junctions to illustrate the strongly correlated phenomena of current-driven dynamics and time-dependent conductance in nanoelectronics, noting implications to, and potential applications in, several disciplines.
