PN diodes-depletion zone

1 post in this topic

Again, sorry for making alot of threads, I just found this forum and I have many questions.

When p and n meet they form a junction. Shortly after a depletion zone is formed.

I have a question about this forming. Probably the obvious answer.

Near the junction, electrons from n-type crossover into p-type and fill those electron holes, leaving their mother atoms(5 valence ones) immobile positive ions, and when acceptors accept those electrons, they become negative ions. Atoms near that depletion zone are immobile, and this recombining of the electrons and holes makes those atoms ionized and this creates that electric field? And because there are no charge carriers there, this is called depletion zone?

Am I thinking right here?
