# Semiconductor Diodes

For the current-voltage characteristic of a p-n diode which is foward biased:

ln i = ln + eV/2kT

where i˚ = a constant current
e = electronic charge
k = Boltzmann constant
T = absolute electron temperature
i and v are current and voltage respectively, for which I have a series of values

I am supposed to plot i against v on semilog paper with i on the log scale, with T calculated from the graph without knowing i˚. Admittedly physics isn't my storng suit and I have thought about this for a long time and have gotten nowhere. I was wondering if somebody could tell me how I am supposed to do this?

Thanks,
