In modern electronics, the terms N-type semiconductor and P-type semiconductor describe two foundational ways to tailor the electrical behaviour of silicon and other semiconductor materials. By introducing tiny amounts of dopants, manufacturers craft materials whose charge carriers are predominantly electrons or holes. The resulting n-type semiconductor and p-type semiconductor form the building blocks of countless…
