Useful for very high doping reverse bias conditions?

I want to know how suitable this tool is for calculating IV characteristics for very high doped pn junctions into the 10(18) – 10(19) /cm3 under reverse bias conditions. It seems like as you increase the carrier concentrations to these high levels there should be more reverse current as the doping increases, but that doesn’t seem to be the case going from 10(17) ranging up to the mid 10(18) s.

If this tool isn’t useful for those kinds of simulations, are there any tools you can suggest?

Thanks.

    Hi, As doping is increased the p-n barrier increases leading to a reduced reverse bias current. Are you trying to see zener effect?

    thanks
