Question

which of the following is the n-type semiconductor? a.pure si b. si doped with As c. Si doped with Ga d. Ge doped with In​

Answer 1

Answer:

(b). Si doped with As

mark as brilliant

Answer 2

The correct answer is Si doped with As. (option b)

• N-Type Semiconductors: In this type of semiconductor, the electron is the majority charge carriers and holes are the minority charge carriers.

• Doping of impurities like Si or Ge into the material forms an n-type semiconductor.
• Doping for n-type can be done using Si with As or Ge with Sb etc.
• Usually n-type consists of free electrons as majority charge carrier, hence the correct answer is Si doped with As.
