Conductance Fluctuations in Thin Metal Films

Abstract
We have observed time dependent conductance fluctuations in thin films of Bi and Pt, at low temperatures. The magnitude of these fluctuations becomes larger as the temperature is reduced, and is in reasonable agreement with the theory of Feng, Lee, and Stone, which ascribes them to the motion of individual scattering centers. The time dependence of the fluctuations is in good agreement with this interpretation.
