Nanodot-Molecule Junctions: Assessing Intermolecular Interactions and Electron Transport at Microwave Frequencies

Here, we present the properties of molecular junctions fabricated on a large array of sub-10 nm single crystal Au nanodot electrodes, each junction being made of less than one hundred molecules. Thanks to this approach, we discuss some pending issues in molecular electronic: (i) the determination of inter-molecular interactions from the conductance histograms of molecular junctions, (ii) the demonstration of molecular electronic devices for high-frequency operation with a molecular diode working in the microwave regime up to 18 GHz.
