Question

Quizplus · Accepted Answer

When Si is doped with P, it produces an n-type semiconductor. This is because P has 5 valence electrons whereas Si has 4 valence electrons. When P is added to Si, it brings an extra electron, which creates an excess of negative charge carriers (electrons) in the crystal lattice, leading to the n-type semiconductor.
