Abstract

The conductance of a single molecule covalently connected to two gold electrodes can be determined by the statistical analysis of many repeatedly created gold-molecule-gold junctions. Conductance histograms reveal well-defined peaks at integer multiples of a fundamental conductance, which is used to identify the average conductance of a single molecule. The large width of the peaks indicates considerable variations in conductance of individual molecular junctions due to difference in the microscopic details of molecule-electrode contacts. Using the method, electron transport properties of a variety of molecules, from N-alkanedithiol molecules to DNA duplexes, have been studied.
