n-type semiconductors can be formed by addition of the elemental metals to the parent compound. For example, addition of Zr to ZrO or Ti to TiO. Like wise, p-type semiconductors can be formed by increasing the amount of the nonmetal In Cu2S (add S), Cul (add elemental I), or ZnO (add O). Explain how this is possible.
