Abstract:
Over the past decade, there has been tremendous progress in the measurement, modeling and understanding of structure-function relationships in single molecule circuits. Experimental techniques for reliable and reproducible single molecule junction measurements have led, in part, to this progress. In particular, the scanning tunneling microscope-based break-junction technique has enabled rapid, sequential measurement of large numbers of nanoscale junctions allowing a statistical analysis to readily distinguish reproducible characteristics. The break-junction technique is mostly used to measure electronic properties of single-molecule circuits. In this talk, I will describe how these experiments work and also provide a detailed physical and chemical background to understand measurement results, focusing on the impact of quantum interferences in these circuits.
