Answer 2

Answer:

Semiconductors are substances whose electrical conductivity lies in between conductors and insulators.

Explanation:

The electrical conductivity of a semiconductor material is intermediate between that of a conductor, such as metallic copper, and an insulator, such as glass. As the temperature increases, its resistivity decreases; metals respond in a reverse way. The material whose conductivity falls between insulators and conductors is known as a Semiconductor. At absolute zero, the semiconductor acts as an insulator, but when thermal agitation is present, charge carriers begin to move from the valence band to the conduction band.

Thus, at low temperatures, a semiconductor acts as an Insulator.
