Question

Which of the following is true of semiconductors? A. Exposing a crystal of a semiconductor to heat or light starts displacing valence electrons, which then move throughout the crystal. B. A material is classified as a semiconductor if its resistance to the flow of electric current is too low to permit it to be called a conductor. C. Neither free electrons nor holes are considered charge carriers in a semiconductor. D. Gold and silver are important semiconductors

Answer 1

Explanation:

semi conductor are more conductive than a non metal and less conductive to metal.

Answer 2

Answer: A -material is classified as a semiconductor if its resistance to the flow of electric current is too low to permit it to be called a conductor is true about semi-conductors.
