TLDR
The composition of the anodic passive oxide film on iron in neutral solution has been investigated by cathodic reduction, chemical analysis and ellipsometry as mentioned in this paper, and it was found that the film retains nearly constant thickness above a critical potential where transpassive dissolution begins to occur.About:

A semiconductor model of the passive layer on iron electrodes and its application to electrochemical reactions
U. Stimming,J.W. Schultze +1 more
TL;DR: In this paper, a semiconductor model of the passive layer was used for the explanation of transfer reactions of electrons (etr) and ions (itr) on passive iron electrodes, which takes place via the conduction band at low potentials and via the valence band at high potentials.

A theory for breakdown of anodic oxide films on metals
TL;DR: In this article, the breakdown of anodic oxide films is described thermodynamically as a mechanical deformation or crack formation, and the breakdown potential at which the film thickness is critical depends on the anion concentration in solution.

TL;DR: In this article, the decay of the polarized passive potential on open circuit is explained as due mainly to the change in the defect-concentration and consequently of the film composition at the oxide/solution interface either by the outward migration of iron through the film or by the reaction with Fe++ ion in solution when the latter had been added or supplied by a small amount of self-corrosion.

Electron Diffraction Studies of Active, Passive, and Transpassive Oxide Films Formed on Iron
TL;DR: In this paper, the epitaxial relationship of the oxide to the iron substrate was determined using selected area transmission electron diffraction (SED) and the authors found that in all of the electrolytes used the passive film contained, while the nonpassive films did not.

Ellipsometry of the passivation film on iron in neutral solution
Norio Sato,K. Kudo +1 more
TL;DR: In this article, the passivation of a passivation film on iron was investigated and it was shown that the film thickness is linearly related to the oxidation potential in a limited potential region, which extrapolates to a film thicker than a monolayer even at zero anode overvoltage.
