- The energy structure of a semiconductor can be altered by substituting one type of atom with another (doping).
- Semiconductor n-type doping creates and fills new energy levels just below the conduction band.
- Semiconductor p-type doping creates new energy levels just above the valence band.
- The Hall effect can be used to determine charge, drift velocity, and charge carrier number density of a semiconductor.
