Abstract :
Electronic transport in metal-alkanethiol-metal junctions is investigated. Using conducting atomic force microscopy we study molecular chain-to-chain tunneling which exhibits molecular tilt dependent intermolecular transport. And molecular devices with nanometer-scale junction area are fabricated and characterized. To clarify the molecular conduction mechanism, temperature-variable current-voltage measurements are performed.
