| Assertion (A): Silicon is preferred over Germanium for making semiconductor devices. |
| Reason (R): The energy gap of Germanium is more than the energy gap of Silicon. |
A) Both A and R are true and R is the correct explanation of A
B) Both A and R are true but R is NOT the correct explanation of A
C) A is true but R is false
D) A is false and R is true
Correct Answer: B
Solution :
| Option [b] is correct. |
| Explanation: Silicon is preferred over Germanium for making semiconductor devices. The assertion is true. |
| The energy gap of Germanium is about 0,7 eV, where as the energy gap of Silicon is 1.1 eV. |
| Hence, the reason is false. |
