- wherein
1) nh >>ne
2) There is an acceptor level just above the valence band .
n - type semiconductor -
Here the base semiconductor (e.g. pure Si or Ge) is mixed with pentavalent doping material
(e.g. Phosphorous)
- wherein
1) ne >>nh
2) There is donor energy level between valence band and conduction band. Just below conduction band.
Holes are nothing but absence of electron from its position.
