Abstract

We report temporal conductance instabilities in the far-from-equilibrium transport through quantum point contacts. Random telegraph switching between conduction states is shown to have a maximum probability when the chemical potential of the injection electrode is close to a subband minimum. We show the RTS in these far-from-equilibrium experiments must have a different origin to that proposed for RTS in near-equilibrium measurements.
