Mesoscopic oscillations of the conductance of disordered metallic samples as a function of temperature

TL;DR

This paper demonstrates both theoretically and experimentally that disordered metallic samples show random conductance oscillations with temperature, where oscillation amplitude decreases as a power law and the period is roughly equal to the temperature.

Contribution

It provides the first combined theoretical and experimental analysis of temperature-induced conductance oscillations in disordered metals.

Findings

Conductance oscillations are observed as a function of temperature.

Oscillation amplitude decays following a power law.

Oscillation period is approximately equal to the temperature.

Abstract

We show theoretically and experimentally that the conductance of small disordered samples exhibits random oscillations as a function of temperature. The amplitude of the oscillations decays as a power law of temperature, and their characteristic period is of the order of the temperature itself.
