Question

Semiconductors those are created by doping an intrinsic semiconductor with donor impurities are

• A. p-type
• B. n-type
• C. may be any of them
• D. none of them

Answer 1

The correct option is B n-type

Donor impurities are the ones that donate electrons to the semiconductor atom. For each donor atom added, there is one electron donated to the semiconductor atom. As a result, the electrons in such type of semiconductors are majority charge carriers. Therefore, this extrinsic semiconductor formed by adding donor impurities are called n-type semiconductors.
