Simulation of metal-oxide metal oxide metal diode

Can someone tell me how can i simulate the quantum tunneling effect in metal oxide metal (MOM or MIM) diodes?

I am thinking about using a microwave based software like CST microwave or ADS to get the electrical fields and subsequently importing them into Matlab to calculate the current density and plot the IV- curve. Don't know if it will work.

Or is there a direct way that how can i simulate MOM or a tunnel diode which also have similar behaviour. which models should i use to simultae these diodes.

Any help would be greatly appreciated.

Thanks

i suggest the best simulation depends on the fabrication parameters used and entered into COMSUL. Wide variations in fabrication molecular ingedients and lower than bulk permitivity is to be expected.

Falstad's animated simulator supports a tunnel diode, with these circuits in the menu:

* I/V curve
* LC oscillator
* Relaxation oscillator

Free to download and use. Or, run it online and choose from the listed circuits.

Look in the menu for Misc. Devices > tunnel diode.

You need to have Java installed on your computer.
