STANDARD Physics Intrinsic and Extrinsic Semiconductors MCQ Question
Intrinsic semiconductor is electrically neutral. Extrinsic semiconductor having large number of current carriers would be
Positively charged
Negatively charged
Positively charged or negatively charged depending upon the type of impurity that has been added
Electrically neutral
Correct Answer
Detailed Explanation
Extrinsic semiconductors (N-type or P-type) are neutral because the charge of the added impurities balances the charge of the carriers.
