For extrinsic semiconductors; when doping level is increased;
Options
Fermi-level of p-type semiconductor will go upward, and Fermi-level of n-type semiconductors will go downward.
Fermi-level of p-type semiconductors will go downward, and Fermi-level of n-type semiconductor will go upward.
Fermi levels of both p-type and n-type semiconductors move upward for T greater than the Fermi temperature and downward for lower T.
Fermi-level of p and n-type semiconductors will not be affected.
