Which of the follwing is the n-type semi-conductor in terms of doping
Correct answer: A. Option A: Silicon
- A. Option A: Silicon
- B. Option B: Germanium
- C. Option C: Gallium
- D. Option D: Carbon
Explanation
The correct answer is Option A: Silicon. When doped with electron-rich impurities, silicon becomes an n-type semi-conductor. This is because the added electrons allow for the flow of current. Options B, C, and D are incorrect as they are not mentioned as specific n-type semi-conductors in the context of doping.

About PN Junction
A PN junction forms when p type and n type semiconductor regions meet, creating a depletion layer and a potential barrier. The topic covers forward and reverse bias, diode current voltage characteristics, breakdown and rectification, while distinguishing an ordinary junction diode from a transistor formed from multiple junctions.
