summary:Molecular electronics is the outermost evolution of conventional microelectronics. It proposes to substitute electronic devices with molecular based ones. The idea behind molecular electronics is that one day the miniaturization of conventional semiconductor devices will reach a technological limit (indeed at the nanometer scale, a molecular relevant scale). This course will waive the many technological issues opposing the building of a truly molecular computer: nature of the contacts, aging..., but rather concentrate of the important fundamental questions that molecular electronic experiments are posing to theory. The course line will follow the chronological experimental trend giving the theoretical instruments for describing electronic conductance in mesoscopic, molecular and biological systems.
