A group in England has developed a very nice idea based on fluctuations [31] here a molecule is chemisorbed on one end to a surface, and a conductive scanning tip is brought to within about a molecule length from the supporting metal. Thermal excitation then permits molecules to form instantaneous transport bridge structures between the planar support and the conductive electrode - one observes fluctuations [Pg.5]

The categories just described compromise the majority of the measurements on molecular transport junctions. [Pg.6]

It is possible to use electronic structure calculations combined with measurements in which the geometry is purposely varied to make some elegant deductions about the adsorption of molecules on the electrodes. A beautiful example is provided by work [Pg.6]

In general, however, many relevant geometric parameters are unknown in molecular transport junctions, and therefore it is necessary to make assumptions, and calculations, to help in understanding the geometry. One interesting approach is [Pg.7]
