N-type crystalline silicon and P-type crystalline silicon
(1) N-type crystalline silicon When crystalline silicon is doped with a small amount of impurity group V elements (such as P), its 5 valence electrons form 4 covalent bonds with silicon atoms, and the V group ion nucleus has one more positive charge, forming a positive center, and one more valence electron. This electron is bound…
