Assertion(A) : Semiconductors are solids...

Assertion(A) : Semiconductors are solids with conductivities in the intermediate range from `(10^(-6)-10^(4)ohm^(-1)*m^(-1))`.
Reason ( R) : Intermediate conductivity in semiconductor is due to partially filled valence band.

A

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

B

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

C

Assertion is corrent statement but reason reason is wrong statement.

D

Assertion is wrong statement but reason is correct statement.

Text Solution

Verified by Experts

The correct Answer is:
C
Corrcet Reason. Intermediate conductivity of semi-conductors is due to small energy gap between valence band (filled) and conduction band (empty band).
