1.For extrinsic semiconductors, when doping level is increaseda.Fermi-level of p-type semiconductor will go upward, and Fermi-level of n-type semiconductors will go downwardb.Fermi-level of p-type semiconductors will go downward, and Fermi-level of n-type semiconductor will go upwardc.Fermi-level of both p-type and n-type semiconductors will go upward for T>TF KT > T_F\,\text{K}T>TFK and downward for T<TF KT < T_F\,\text{K}T<TFK, where TFT_FTF is Fermi temperatured.Fermi-level of p-type and n-type semiconductors will not be affectedLogin to continueOnly logged in users canattempt or see the solution.
