Abstract

We have observed low-frequency discrete resistance switching noise in a Si modulation-doped GaAs/ A!GaAs narrow MODFET. Resistance measurements were done at 1.5 and 4.2K as a function of applied magnetic field B to understand the origin of the resistance fluctuations. The noise magnitude diminishes rapidly as the field is increased and also decreases as the temperature T is raised. This can be understood in terms of strongly correlated spontaneous emptying and filling of ensembles or clusters of interacting localized electron states. The effect of increasing B or T is to weaken the interactions ultimately giving away to individual states fluctuating between two metastable configurations. Any relation of this noise to quantum interference effect is unclear.
