Here's the derivation; I hope it's not late {L_p} = diffusion length of holes ({cm}) {D_p} = diffusion constant ({cm^2}/s) {L_p} = average carrier life time (s) Firstly, we find \Delta{p} where \Delta{p} is the minority carrier concentration at the edge of the depletion region (DP)...

If there's a point charge at the origin, I want to find two closed surfaces such that the flux through one of them is zero while the other is not. I know this may seem trivial but I just want to make sure I understand the question. My answer would be that to get a zero flux, the closed...

I don't think it's possible to get to that equation through a simple derivation. I remember that the continuity equation must be used (in one dimension, for simplicity) and then incorporate boundary conditions and these definitely are not simple. so you might need to reference the whole...
