WebThese positive charges are strong enough to attract free electrons if the block is joined to N-Type silicon. Questions: (1) If the positive charges in a silicon lattice are created by protons, where did these additional positive charges come from, since no additional protons have been added to this block of P-Type silicon? WebEach added boron atom creates a deficiency of one electron—that is, a positive hole. A p -type semiconductor is one with a preponderance of holes; an n -type semiconductor has a preponderance of conduction electrons. The symbols p and n come from the sign of the charge of the particles: p ositive for holes and n egative for electrons.

WebMar 20, 2024 · No, n-type semiconductors and p-type semiconductors are not positively and negatively charged respectively.
