Temperature dependence

Can someone please explain to me the low frequency behavior of the CV curve at low temperature? Is the jumping around in depletion and inversion part of the underlying physics or is it a result of how the numerical methods are performed?

Also, isn’t there some sort of temperature dependence for minority carrier lifetime? If so, does MOSCap take that into account? Thank you very much.

By the way, this is a very helpful program and I appreciate all the work put into it. I know its not trivial work and people shouldn’t complain if it doesn’t do exactly what they need especially since it is free.

    Hi, It is numerical issue. Low temp calculations most of the time have issues with convergence. I think you can vary the minority carrier lifetime in the input and it is used as a constant number in the code.
