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