comment Ionized Depletion Region, Why aren't those charged being excited?
Thanks! I guess my last real question is.....the energy band for the acceptor atoms....is that the energy needed for? What...a electron to fall into a hole? Or does an electron to fall into a hole need a ton of energy? I guess on the other end im not really sure what that energy level on the P-Side would mean?

Ah gotcha, so the Donors atom energy level is right below the conduction band which is why it requires so little energy to go to the conduction band. Ok finally getting it all. Thanks for being patient haha.

Is this because Electrons on the Donor atoms are already sort of "in" the conduction band? (I didn't realize this before, but since it's an extra electron it's going to not be in the valence band i'd assume?)

I mean the energy required to remove an electron from an atom, that energy is much lower on a Donor atom (nside) than an Acceptor Atom (pside)

Ok So basically the de-ionization of an acceptor atom in the p-side requires a much higher energy to deionize put simply?

comment Ionized Depletion Region, Why aren't those charged being excited?
I guess im confused (sorry) if the energy gap is the same (on the p-side and n-side) ~1eV....then the P-Side should be releasing the electrons from the acceptor atoms too? since the n-side did that at room temperature. or are u saying the energy required for the N-side to ionize a electron is much lower than the p-side? (Im confused because u said the energy gap was the same.....which if it was, both the p-side acceptor atoms, and n-side donor atoms would release electrons at room temp)

Ah, but the thermal energy required for the N-Side dopants to release electrons is much lower correct? Since it happens at room temp anyways?

Oh thats what I meant, that once the depletion region was formed...how often a Acceptor atom de-ionizes.

comment Ionized Depletion Region, Why aren't those charged being excited?
Makes sense, but can you answer one quick question: In the scenario that you mentioned (Which makes sense). How often would this de-ionization happen? Or do typically the electrons in the P-Side stay with their respective Atoms? Because if it happened alot...it seems like the depletion region would be unstable (as in shifting alot) since electrons would be popping in and out alot.

@boyfarrell awesome! looking forward to it!

comment Ionized Depletion Region, Why aren't those charged being excited?
@boyfarrell thats a fair rewording. Because im mainly concerned with why at room temp electrons are being ionized....but still being trapped with the acceptor atoms. But I also suppose I wonder why electrons aren't filling the donor atoms either (but Im assuming thats because of electric field....which makes sense)
