Can an electrostatic field be used to create an oxide layer that has a permanent electric field?

For a specific example; an aluminium domed van de graaff generator with no oxide layer. If it is turned on and allowed to contact oxygen, would the oxide layer store a permanent electric field?

There are devices called electrets that have a permanent electric field, like a permanent magnet has a permanent magnetic field. The dielectric layer in a charged capacitor has a "permanent" electric field, at least until leakage currents neutralize the charge.

Yes I know; but, can one be made in the manner I described?

I don't think so. I think the applied electric field in an oxide grown in this fashion would just relax when you took away the applied field. Why should it persist?
