MHT CET Physics question

Not in JEE Advanced syllabus

The behaviour of Ge as semiconductor is due to the width of:

(A)Conduction band being large
(B)Forbidden band being large
(C)Conduction band being small
(D)Forbidden band being small and narrow.Correct

Answer: (D)

Solution

Germanium behaves as a semiconductor because its forbidden gap is small and narrow (0.7 eV), so thermal energy lifts some electrons into the conduction band;
