Resum
Several breakdown events and multilevel current fluctuations have been observed when ultrathin SiO2 films are subjected to constant-voltage stresses. These breakdown events are sometimes reversible, and consist in a local change of conduction mechanism. This reversibility shows that no catastrophic thermal effects occur, and that the breakdown is only a local switching between two oxide conduction states of very different conductivities.
