Abstract
Electronic transport studies of mesoscopic systems may yield unique information on a variety of physical processes. Here we discuss results of transport measurements on electron-glasses with sizes approaching the mesoscopic regime of hopping conductance. The study reveals fluctuations in the conductance as function of the gate voltage in samples that are smaller than ≈100μm, when measured at liquid helium temperatures. The relative amplitude of the conductance fluctuations decreases with the sample volume while, down to sample size of few microns, the non-equilibrium features that are attributed to the electron-glass are indistinguishable from those observed in macroscopic samples. These include the memory-dip, slow relaxation, and simple-aging behavior. The mesoscopic conductance fluctuations, as well as the 1/f noise, appear to be different phenomena, independent of the electron-glass dynamics.
