Molecular Electronics

We are interested in charge transfer phenomena in single molecules and work on the forefront of single-molecule and biomolecular electronics.  By advancing scanning probe microscope techniques, we have developed methods to measure electrical transport in a single molecule covalently bonded to two electrodes.  Besides electrical property, our technique enables measurement of mechanical, thermal and chemical properties of a variety of molecules such as alkanes, DNAs, proteins and graphenes. Our current research focuses on a number of key areas: 1) investigating fundamental issues in single-molecule electronics, 2) working towards single-molecule electronic devices, 3) enabling biological and chemical sensing devices based on small numbers of molecules.
