In a simplified model of un doped semiconductor, the actual distribution of energy states may be replaced

Question:

In a simplified model of un doped semiconductor, the actual distribution of energy states may be replaced by one in which there are Nv states in the valence band, all these states having the same energy Ev, and Nc states in the conduction band, all these states having the same energy Ec. The number of electrons in the conduction band equals the number of holes in the valence band.
(a) Show that this last condition implies that

(b) If the Fermi level is in the gap between the two bands and its distance from each band is large relative to kT, then the exponentials dominate in the denominators. Under these conditions, show that

And that, if Nv Nc, the Fermi level for the un doped semiconductor is close to the gap's center.

Distribution
The word "distribution" has several meanings in the financial world, most of them pertaining to the payment of assets from a fund, account, or individual security to an investor or beneficiary. Retirement account distributions are among the most...
