What to Focus On
- Semiconductors replaced bulky vacuum tubes in electronic devices
- Energy band theory explains electrical properties of materials
- Semiconductors have small forbidden energy gaps (~1 eV)
- Pure semiconductors have equal numbers of electrons and holes
- Conductivity increases with temperature due to more charge carriers
- Holes behave as positive charge carriers
- Doping with pentavalent atoms creates n-type semiconductors
- Doping with trivalent atoms creates p-type semiconductors
- Majority carriers determine the type of semiconductor
Common Mistakes to Avoid
In a p-n junction diode, current flows from p-side to n-side in forward bias because holes physically move from p to n
Doping always increases conductivity of a semiconductor
The depletion region in a p-n junction contains no charges at all
