The conduction band in semiconductors is generally separated by an energy gap from the valence band edge. They don't overlap with each other.
It is important to clean, sanitize and store our equipment properly.
Explanation:Because we clean our surrounding for our safety from bacteria's. We sanitize to make it more cleaner or in other words to protect our health. We store our products properly so that it doesn't make any more trouble like we were finding something we use and our products properly stored and because of that you don't need to find anymore.
Hope it helps.
