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