Find the Schottky diode barrier height and the ideality...

Homework Statement

Using the diode equation with moderate forward bias, show numerically how to find the Schottky diode barrier height and the ideality factor via a graphical plot.

Homework Equations

I = I0e(eV/nkT)
I0= AA*T2e-eφb/kT

with n= ideality factor
and φb= Barrier height

The Attempt at a Solution

I tried to look at the plot of ln(I) against V and assumed this would be a straight line graph and so the gradient can be rearranged such that n= eV/kT (ln(I/I0)).

And also they y intercept would just be ln (I0) and I can use this to rearrange and find the barrier height.

I'm not sure if any of this is right, I don't like that I've had to assume a straight line graph, any guidance would be much appreciated!

Thanks
