Physics Semiconductor Electronics MHT CET

Not in JEE Advanced syllabus

In extrinsic semiconductors,

(A)The conduction band and valence band overlap
(B)The gap between conduction band and valence band is more than 16 eV
(C)The gap between conduction band and valence band is near about 1 eVCorrect
(D)The gap between conduction band and valence band will be 100 eV and more

Answer: (C)

Solution

Doping does not change the order of the band gap, which stays about 1 eV; overlapping bands (a)
