研究领域

One of the central themes in Nanoscience is Molecular Electronics which aims to reach the next level of miniaturization of electronic components. My research focuses on the requirements needed to translate single-molecule electronics from a fundamental tool to a practical technology. Using scanning probe microscopy approaches combined with surface chemistry and electrochemical techniques my research aim to enhance the physical and chemical properties of the contact between single molecules and electrodes. A key approach is the use of new electrode-molecule anchoring strategies including the integration of single-molecule junctions with the industrially dominant silicon electronics and the utilizations of chemistries whose electronic properties lead to a device-performance beyond conventional electronics.
