The newest developments in microelectronics, energy conversion, and sensing device design are tied very closely to our ability to selectively modify well-defined surfaces by chemical means. In particular, in the last years the passivation and functionalization of semiconductor surfaces have become a target for the realization of novel devices. We aim to develop new hybrid systems where molecular and electronic control of the structure is key. The project focus on the application of organophosphonate chemistry for covalent surface modification of emerging carbon semiconductor substrates, like silicon carbide, diamond and graphene. The applicability of organophosphonate chemistry will be further investigated with respect to generation of three-dimensional, organized multilayers, and supramolecular arrays on these substrates. Finally we aim to apply this novel approach to the optimization of nanodevices, in particular with respect to applications in biosensing.
