This has no transistor effect at all. If it had, every capacitor
would be a transistor.
Perhaps every *unsealed* capacitor would act like a resistor.
Resistor for RF yes, transistor no. A transistor is an active
component, while a resitor or a capatitor is not.
I also have never heard of MOM stransistrs, only MOS.
Okay, then think of as a a really large diode, where the oxidized metal surfaces form the semiconductor material.
Since when does oxydized metal have semiconductor-properties?
In fact in a MOS-FET, the metal oxyde froms the insulator, just like
the PN-junktion in a JFET.
The key to MOS transistors is a semi-conductor that has movable
electrons and can be made more or less conducting by applying an
external electric field.

The references I used are proprietary.
If you are seriously interested then I recommend:
- search Google for references on "passive intermodulation" or "PIM"
- pick up a copy of the conference report by the European Space Agency: Multipactor, RF and DC Corona and Passive Intermodulation in Space RF Hardware", 4-6 September 2000, ESTEC, Noordwijk, The Netherlands.
Aha, now I know what you are talking about! (Roughly, as this RF
stuff is in part black magic in my eyes.) This is not about an
active element, but rather a passive mixer/modulator/resonator-effect.
Yes that could certainly happen with isolated strips of conducting
material.
