Diode Current Manipulation
Not what you're looking for?
A schottky diode and a pn junction diode have cross sectional areas a=10^-4. The reverse saturation current density of the pn junction diode is 3x10^-8 A/cm^2. The reverse saturation current density of the pn junction diode is 3x10^-12A/cm^2. Determine the forward bias voltage in each diode required to yeild diode currents of 1mA.
If I use Jst=A*T^2*exp( (-q*phi|bn) / KT) to find the voltage for the Schottky diode, how do I find phi|bn from the given information?
IF I use J=q*Dn*npo/Ln+q*Dp*pno/Lp. How do I determine Ln, Lp, npo, pno, Dn, and Dp from the given information?
Thank you.

This is a bit ambiguous. That's okay.
Here is a simple and straightforward solution to the problem.
I am not sure why you need all these complicated equations, I will give you a simple solution and I am sure it's right.
Although the current mechanisms in ...
