How is this equation derived?

[Turion]

Equation in pink:

I was absent so I was going through the slides and I saw that equation. There isn't a derivation shown. Do you guys have any ideas?

What course is this?

What do the symbols mean?

This is for solid state physics.

n₀ represents the number of electrons in a semiconductor. p₀ represents the number of holes in a semi conductor.

N_A represents the number of positive (acceptor) ions. N_D represents the number of negative (donor) ions.

n_i=p_i=n₀=p₀ in an instrinsic semiconductor.

Maybe you could start with the density of states.

If you Google "carriers doped semiconductor", 7 out of the top 7 results will lead you to a derivation. I stopped counting at that point. http://ecee.colorado.edu/~bart/book/extrinsi.htm is the first.
