We mention the best known, which defines the non-equilibrium noise temperature T n pivotal to the interpretation of device-noise data [41]. Phenomenologically T n is obtained, for a non-linear operating point, by normalizing S f with the differential conductivity σ…”

We analyze high-field current fluctuations in degenerate conductors by mapping the electronic Fermi-liquid correlations at equilibrium to their semi-classical non-equilibrium form. Our resulting Boltzmann description is applicable to diffusive mesoscopic wires. We derive a non-equilibrium connection between thermal fluctuations of the current and resistive dissipation. In the weak-field limit this is the canonical fluctuation-dissipation theorem. Away from equilibrium, the connection enables explicit calculation of the excess "hot-electron" contribution to the thermal spectrum. We show that excess thermal noise is strongly inhibited by Pauli exclusion. This behaviour is generic to the semi-classical metallic regime.73.50. Td, 72.10.Bg, 73.50.Fq

“…Cette relation, donnée dans la référence [3], avait déjà été établie pour des types particuliers de sources de bruit [4,5]. En intégrant l'équation (11) dans la tranche àx' = Ax, on obtient la relation liant la source de bruit locale Kx(r, f ) dans la direction x, et le courant de bruit SIx(r, f ), dans la direction x, à travers la tranche située en r : La méthode expérimentale de détermination de la source locale de bruit découle de la relation (12) [6,7]. Puisque Tn est reliée à SI (cf.…”
