Assertion :-(A) semiconductors are so...

Assertion :-(A) semiconductors are solids with conductivites in the intermediate range from`10^(-6)-10^(4) ohm ^(-1)m^(-1)`
Reason :-(R ) internmediate conductivity in semiconductor Is due to partially filled valence band .

A

Assertion and reason both are correct statements and reason is correct explanation for assertion.

B

Assertion and reason both are correct statements but reason is not correct explanation for assertion

C

Assertion is correct statement but reason is wrong statement

D

Assertion is wrong statement but reason is correct statement.

Text Solution

Verified by Experts

The correct Answer is:
c
Correct Reason. Intermediate conductivity of semiconductors is due to small energy gap between filled valence band and empty conduction band.
