The upper level of valence band and lower level of conduction band overlap in the case of
- A silicon
- B copper
- C carbon
- D germanium
Answer & Solution
Correct Answer
(B) copper
Step-by-step Solution
Detailed explanation
There is no forbidden energy gap between conduction bond and valence band for a conductor (copper). Hence, in copper, valence band and conduction band are overlapped.
