Question

Which of the following is true about extrinsic semiconductors?

• A. 0.95
• B. 1.5
• C. 19
• D. (19)^–1

Answer 1

Answer: (A), (D)

The correct options are
A 0.95
D (19)^–1

In n-type semiconductor, a large number of free electrons is present. Hence, free electrons are the majority charge carriers in the n-type semiconductor. In p-type semiconductor, a large number of holes is present. Hence, holes are the majority charge carriers in the p-type semiconductor. The holes (majority charge carriers) carry most of the electric charge or electric current in the p-type semiconductor.
