Match the List I with List II

 List I List II
AIntrinsic SemiconductorIFermi-level near valence band
Bn-type semiconductorIIFermi-level at middle of valence and conduction band
Cp-type semiconductorIIIFermi-level near conduction band
DMetalsIVFermi-level inside conduction band

Choose the correct answer from the options given below:

Options:

Answer:
C
Solution:

(A) The Fermi-level in an intrinsic semiconductor is nearly midway between the conductive and valence band.So, A→II.

(B) In the case of n-type semiconductor, the Fermi level is present just below the conduction band. So, B→III.

(C) Fermi level in a p-type semiconductor lies close to the top of the valence band. So, C→I

(D) In metals and semimetals the Fermi level lies inside at least one band i.e., inside conduction band. So, D→IV.
