1. The problem statement, all variables and given/known data

Hi, I have a problem to find the reverse saturation current for a piece of diode.
I have a question - given conductivity, a I-V curve with forward bias information (a table of I vs V values), how can i proceed? I have other information abt the diode such as its mobility, and then it is made of silicon - other material info assume given.

Anyone can advise the approach? thanks.



2. Relevant equations



3. The attempt at a solution

Where is the relevant equation?
If your data are precise, substitute the values of one point of the curve (V-I) into the diode equation and obtain Is.
If your data are real, they should have measurement errors and you should use the diode equation in conjunction with a filter to obtain Is.

Use the Shockley Diode equation, that should yield an answer.
