Quantum transport in nanostructures is of fundamental interest for studying nonequilibrium quantum physics at the nanoscale and holds potential for future applications in nanoelectronic devices. A versatile architecture to investigate quantum transport processes at the nanoscale is provided by molecular junctions. Consisting of a single molecule bound to electrodes, molecular junctions are among the smallest electrical circuits. Recent experimental and theoretical studies of molecular junctions have revealed a wealth of interesting transport phenomena.
In this talk, mechanisms that determine quantum transport at the molecular scale are discussed based on theoretical studies. This includes co-tunneling and resonant transport processes, quantum interference and decoherence as well as current fluctuations. Furthermore, the important role of electronic-vibrational interaction is analyzed, an aspect that distinguishes nanoscale molecular conductors from mesoscopic devices and is crucial for their mechanical stability.
