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. This technique is also used to identify inelastic scattering from local defects that are tunable with a gate voltage. In the case of LSMO nanowires, competition between conducting and insulating domains exist in the same crystal and at the same time. This manifests as random telegraph noise in electron transport experiments. This noise gives information on the lifetime, genesis, memory, and size of the domains, which arise from competing microscopic processes that are energetically degenerate at low temperatures.
