Assertion (A): We cannot form a p-n junction diode by simply taking a slab of a p-type semiconductor and physically pressing it against another slab of an n-type semiconductor. Reason (R): In a p-type semiconductor, the concentration of holes (nh) is much greater than the concentration of electrons (ne), while in an n-type semiconductor, ne >> nh.
