title: On the photo-induced charge-carrier generation within monolayers of self-assembled organic donor-acceptor dyads.
abstract: By means of STM and nc-AFM the self-assembly of a new donor-acceptor (DA) dyad molecule on highly oriented pyrolytic graphite is identified and compared to molecular simulations. Kelvin probe force microscopy (KPFM) measurements clearly show the photovoltaic activity of this model system under illumination. The optoelectronic properties and the local morphology of the DA dyad assembly are simultaneously probed by KPFM down to the level of one molecular monolayers.
