During the p-n junction formation, when an electron diffuses from n → p, it leaves behind an:
Ionised donor on n-side
When an electron diffuses from the n-side to the p-side in a p-n junction, it leaves behind a positively charged ionised donor atom in the n-region. These immobile positive charges create the depletion region. Thus, the correct answer is (b).
