inverse modeling is deriving c-v curve from the charge disterbution with depth inside the semiconductor substrate of MIS

theoretical solution of possion equation in the semiconductor of an MIS with matlab script...

What do you meen by 'MIS' ?

Metal_Insulator_Semiconductor

First you need to calculate the response of your model with a given set of parameters P.

Then you create a function f(P,c_exp,v_exp) that evaluates the error between your model and the experimental values: you can define it analogously at the least square method.

Finally you can use the Matlab function "fminsearch" to solve the minimization problem of f(P).

Dear Gilles Arnold

thank you very much for your informative answer
