We add impurities such as,_ we can gain an N-types semi-conductors:
Correct answer: A. Antimony, phosphorous or Arsenic
- A. Antimony, phosphorous or Arsenic
- B. Carbon, oxygen and Nitrogen
- C. Arsenic and oxygen
- D. None of these
Explanation
We can gain an N-type semiconductor by adding 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 Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
