Question

In n-type semiconductors, which one is the majority charge carriers?

(a) Holes

(b) Protons

(c) Neutrons

(d) Electrons

I had been asked this question in an interview for job.

The origin of the question is Extrinsic Semiconductor topic in chapter Semiconductor Electronics : Materials, Devices and Simple Circuits of Physics – Class 12

Answer 1

The correct answer is (d) Electrons

The best I can explain: In n-type semiconductors, electrons are majority charge carriers. It is made by adding an impurity to a pure semiconductor. This is the opposite scenario of p-type semiconductors where electrons are the minority charge carriers.
