Intrinsic Semiconductors |
(i) n-type semiconductor : When a pure semiconductor is doped with a pentavalent impurity, we obtain a n-type semiconductor. (ii) p-type semiconductor : When a pure semiconductor is doped with a trivalent impurity, we obtain a p-type semiconductor. |
Semiconductor Diode | A semiconductor diode, the most commonly used type today, is a crystalline piece of semiconductor material with a p-n junction connected to two electrical terminals. |
