A hole diffuses from the p-side to the n-side in a p-n junction. This means that
Text Solution
Verified by ExpertsThe correct answer is:
C
When a hole moves from 
-side to 
-side, actually an electron from 
-side moves to 
-side to fill the hole.
Thus, a bond breaks on the n -side and the freed electron moves to complete a broken bond on the p -side.
