Physics · Semiconductor Electronics
Given below are two statements, one labelled as Assertion (A) and the other labelled as Reason (R). Assertion (A): In an n-type semiconductor, the number density of electrons is much greater than the number density of holes, but the crystal maintains overall charge neutrality. Reason (R): The net charge of electrons contributed by the donor atoms plus the intrinsic electrons is exactly balanced by the net positive charge of the ionized donor cores and holes. Select the correct answer from the options given below.
