MHT CET Physics question

Not in JEE Advanced syllabus

Statement 1: The energy gap between the valence band and conduction band is greater in silicon than in germanium Statement 2: Thermal energy produces fewer minority carriers in silicon than in germanium

(A)Assertion is True, Reason is True; Reason is correct explanation for Assertion
(B)Assertion is True, Reason is True; Reason is not correct explanation for AssertionCorrect
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is True

Answer: (B)

Solution

Both statements are true ( of Si is 1.1 eV and of Ge is 0.7 eV, and Si has fewer thermally generated
