Inelastic scattering effects and electronic shot noise

For the study of junctions formed by single molecules shot noise offers interesting new information that cannot be easily obtained by other means. At low bias it allows, for some cases of interest, determining the transmission probability and the number of current carrying conductance channels. By this method it is possible to identify the cross-over in sign of the inelastic scattering signal in the differential conductance. This is a first step towards the study of inelastic scattering signals in shot noise, as the second moment of the current.
