The technique of nonequilibrium superconducting tunnel spectroscopy is performed on carbon nanotube devices, and after subsequent deconvolution, the nonequilibrium distribution function is calculated. The distribution function provides information on how electrons interact as they traverse the nanotube, and its spatial dependence indicates whether electron transport is ballistic or di usive.

In the case of LSMO nanowires, competition between conducting and insulating domains exist in the same crystal and at the same time.
