For extrinsic semiconductors; when doping level is increased
For extrinsic semiconductors; when doping level is increased
Option 1 -
Fermi-level of p and n-type semiconductors will not be affected.
Option 2 -
Fermi-level of p-type semiconductor will go upward and Fermi-level of n-type semiconductors will go downward.
Option 3 -
Fermi-level of p-type semiconductors will go downward and Fermi-level of n-type semiconductor will go upward
Option 4 -
Fermi-level of both p-type and n-type semiconductors will go upward for T > TF K and downward for T < TF K, where TF is Fermi temperature.
