For extrinsic semiconductors; when doping level is increased;

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 p and n-type semiconductors will not be affected.

Fermi-level of both p-type and n-type semiconductors will go upward for $\displaystyle \mathrm{T}>\mathrm{T}_{\mathrm{F}} \mathrm{K}$ and downward for $\displaystyle \mathrm{T}<\mathrm{T}_{\mathrm{F}} \mathrm{K}$, where $\displaystyle \mathrm{T}_{\mathrm{F}}$ is Fermi temperature.
