Modern Physics for Engineers Lecture slides 21b – Semiconductor doping and diodes

This lecture part discusses n-type and p-type doping in semiconductors and the resulting diodes that can be formed in this way. It also discusses that Fermi levels are equalized when such materials are joined together, because of the movement of electrons and holes to equalize their chemical potentials (Fermi levels), and shows the resulting band diagrams for diodes.
