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.

About Electrical Properties of Solids
Electrical properties of solids depend on their band structure, charge carriers and conductivity. The topic compares conductors, insulators and semiconductors, relates resistivity to temperature, and covers intrinsic and extrinsic semiconductors, donor and acceptor impurities, electron and hole conduction, and the formation of p-type and n-type materials.
