Abstract
Large fluctuations of conductivity with time are observed in a low-mobility two-dimensional electron system in silicon at low electron densities n s and temperatures. A dramatic increase of the noise power (∝1/ f α ) as n s is reduced below a certain density n g, and a sharp jump of α at n s≈ n g, are attributed to the freezing of the electron glass at n s= n g. The data strongly suggest that glassy dynamics persists in the metallic phase.
