Single molecule junctions

Bottom-up electronics based on single-molecule transistors can constitute a viable alternative to top-down semiconducting electronics. We are interested in the key signatures of electronic transport through single-molecule transistors. Also topographic features as revealed im STm set-ups are investigated.
