The germanium or silicon crystal formed after adding pentavalent impurity is known as _ substances.
Correct answer: A. N-type
- A. N-type
- B. S-type
- C. Q-type
- D. None of these
Explanation
We can gain an N-type semiconductor by adding pentavalent impurities such as phosphorus or arsenic. These elements have more electrons in their outer shells than elements like silicon or germanium, and when they're introduced as impurities into these semiconductors, they create an excess of free electrons, thereby giving rise to an N-type semiconductor.
