This has no transistor effect at all. If it had, every capacitor 
would be a transistor. 

I also have never heard of MOM stransistrs, only MOS.

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.

Should I be mistaken, please provide a reference for "MOM Transistors"
