The current–voltage characteristic curve for a semiconductor diode as a function of temperature T is given by

I = I o ( e e Δ V / k n T 1 )

Here the first symbol e represents Euler’s number, the base of natural logarithms. The second e is the magnitude of the electron charge, the kB stands for Boltzmann’s constant, and T is the absolute temperature. (a) Set up a spreadsheet to calculate I and R = ΔV/I for ΔV = 0.400 V to 0.600 V in increments of 0.005 V. Assume I0 = 1.00 nA. (b) Plot R versus ΔV for T = 280 K, 300 K, and 320 K.
