Question

For extrinsic semiconductors; when doping level is increased;

Select the correct option:

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-level of both p-type and n-type semiconductros will go upward for T > TF K and downward for T < TF K, where TF is Fermi temperature.

Fermi-level of p and n-type semiconductors will not be affected.
