Electronics with Molecules

The ability to understand, control, and exploit the flow of electronic charge through single or small organized arrays of molecules represents an ultimate dream of physicists, chemists, materials scientists, and device engineers. This chapter addresses some of the formal, computational, and device-level issues facing molecular electronics – specifically, how to model current flow through various molecular components in their diverse transport regimes, how the computed results measure up with available experiments, how they advance our fundamental understanding of nonequilibrium quantum physics, and how we could utilize this understanding to do potentially useful electronics with molecules.
