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.
I = I0e(eV/nkT)
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!
