Question

Identify the property which is not characteristic for a semiconductor?

• A. at a very low temperatures, it behaves like an insulator
• B. at higher temperatures two types of charge carriers will cause conductivity
• C. the charge carriers are electrons and holes in the valence band at higher temperatures
• D. the semiconductor is electrically neutral.

Answer 1

Answer: (C)

the charge carriers are electrons and holes in the valence band at higher temperatures

For semiconductors, in conduction band the charge carriers are electrons and holes at higher temperatures.
