I need to determine the energy gaps of silicon and germanium transistors using a recorded temperature value range and changes in the reverse saturated current for this range.
The equation given is of the form:
Is = A exp (-Eg/kT)
Is = reverse saturated current
A = a constant
Eg = energy gap of the semiconductor
k - Boltzmann constant
T = absolute temperature
I know I need to construct a graph using the Is and T values gathered, and then use the gradient of this graph, but I can't seem the rearrange the equation for Eg where this is possible. The constant 'A' seems to be causing the trouble.
For each transistor the reverse bias volatage was also noted.
