Physics · JEE | Semiconductor Electronics: Materials, Devices and Simple Circuits

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Elemental semiconductors like Silicon and Germanium have diamond-like structures where each atom is surrounded by four nearest neighbours sharing covalent bonds. Reason (R): At absolute zero temperature (\( T = 0 \text{ K} \)), intrinsic semiconductors conduct electricity very efficiently due to high thermal agitation. In the light of the above statements, choose the correct answer from the options given below:

1. A
   Both (A) and (R) are true and (R) is the correct explanation of (A).
2. B
   Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
3. C
   (A) is true but (R) is false.
4. D
   (A) is false but (R) is true.
