Abstract
A field-effect conductance-modulation experiment has been performed on ultrathin films of metals deposited onto amorphous germanium substrat es. For the thinnest films at the lowest temperatures, the conductance exhibits logarithmic decay, memory, aging, and hysteretic effects in its response to changes in fate voltage. These glasslike phenomena dis appear above a characteristic temperature, and become impleasurable as film thickiness is increased.
