An electron diffusing from n-side to p-side leaves behind:
AA mobile hole on the n-side
BA free electron on the p-side
CAn immobile positive donor ion
DAn immobile negative acceptor ion
Answer & Solution
Correct answer: C. An immobile positive donor ion
The donor that lost its electron is a positive ion bound in the lattice, so it cannot move.
