Summary:A recent concept of local noise sensor is extended to measure the energy resolved electronic energy distribution \(f(\varepsilon)\) at a given location inside a non-equilibrium normal metal interconnect. A quantitative analysis of \(f(\varepsilon)\) is complicated because of a nonlinear differential resistance of the noise sensor, represented by a diffusive InAs nanowire. Nevertheless, by comparing the non-equilibrium results with reference equilibrium measurements, we conclude that \(f(\varepsilon)\) is indistinguishable from the Fermi distribution.
