Question

The Fermi energy of an n-type si semiconductor is lower than that of a p-type si semiconductor true or false

Answer 1

extrinsic semiconductor the number of electrons in the conduction band and the number of holes in valence band are not equal .therefore the Fermi level for the extinction semiconductor lives close to the conduction or valence band

in n type semiconductor pentavalent impurity is added therefore the Fermi level of N type semiconductor is lies close to the conduction band
