Title: some gate-source point did not convergence in IV characteristic
Post by: njuxyh on February 27, 2019, 08:31

Dear ALL:
there are two points in gate-source plot did not convergence. see the following figure.
 so i am wondering  how to recalculate the two convergenced points?
and then merge the other convergence points together once again
 to get  the on/off ration and other physical values?

It really depends on why they did not converge, but if we assume that they were close to converging, I suggest that you use the function "setCalculator", to set a slightly different calculator for those points and then run ".update()" again. This will only recalculate those points, with the new calculator. See the manual page for details: https://docs.quantumatk.com/manual/Types/IVCharacteristics/IVCharacteristics.html

Take a look at this tutorial: https://docs.quantumatk.com/tutorials/ivcharacteristics/ivcharacteristics.html, you may also watch a webinar on "New Framework for IV Curve Simulations" at https://docs.quantumatk.com/webinars/webinars.html.

thank you. now i am trying to do according to the manual.
