General Physics Interview Question:

Why is n-type conductor is neutral?

Submitted by: Administrator

N-type semiconductors are prepared by doping pentavalent
atom (e.g. phosphorus) with the intrinsic semiconductor. we
know that atoms are neutral. out of five electron of P-atom
four makes covalent bond. one of the electron is only free
to move. it is remains in the material not escaping so the
n-type semiconductor material is neutral.
