Plasmonic nanoantennas are a revolutionary tool to focus visible light
down to the 10nm regime - and thereby substantially past the diffraction
limit. This improves drastically the coupling efficiency and optical
field intensities relative to conventional Near Field Optical
techniques. The goal of this cooperation is to establish a novel
instrumentation for reproducibly measuring electronic transport through
single molecules while simultaneously coupling light into these
molecules, thus allowing us to investigate the interaction of individual
photons with molecular electronic states. It is therefore crucial to
combine advanced near field optical methods with the most reliable
techniques for measuring transport characteristics through individual
molecules. Therefore we want to combine the expertise at LBL and TUM by
placing optical antennas on conventional Near Field probes that have
successfully been used in the past to investigate single molecule junctions.
