Question

Statement I: By doping silicon semiconductors with pentavalent material, the electrons density increases. Statement II: The n - type of semiconductor has a net negative charge. In the above statements, choose the most appropriate answer from the options given below:

TestHub · Accepted Answer

Pentavalent material has excess free e - because we mix the impurities like phosphorus and arsenic having five electrons in the outermost shell. So e - density increases, but overall semiconductor is neutral. So we can say that Statement I is true but, Statement II is false.
