Charge Transport in Disordered Molecular Systems

How does classical reality emerge from quantum mechanics? When does an electron in a molecule stop behaving as a wave and start behaving as a particle? What is the best way to describe the intermediate regime? Can quantum mechanical effects be put to practical use in molecular electronics? These are the questions that this thesis asks and attempts to answer. The topics covered include quantum interference and decoherence in molecular systems, band-like and incoherent hopping charge transport in polymers, the effects of the molecular environment on single-molecule charge transport and supramolecular control of charge transport
