For extrinsic semiconductors; when doping level is increased

Option 1 -

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

Option 2 -

Fermi-level of p-type semiconductor will go upward and Fermi-level of n-type semiconductors will go downward.

Option 3 -

Fermi-level of p-type semiconductors will go downward and Fermi-level of n-type semiconductor will go upward

Option 4 -

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

ibattery= 1 0 ? 3 1 0 0 0  = 7mA

i2kW = 3 2 0 0 0  =1.5 mA

iz = (7 – 1.5) mA

= 5.5mA
