Question

Semiconductor is substance which act as has conductor at high temperature and as good conductor at low temperature.True (or) false​.

Answer 1

Answer:

false

Explanation:

semiconductors are good conductors at high temperature and insulators at low temperature.

Answer 2

A semiconductor is a substance which act as has conductor at high temperature and as an insulator at low temperature. - False​.

Explanation:

• Semiconductors are materials with conductivity intermediate between conductors (usually metals) and non-conductors or insulators (such as ceramics).
• Semiconductor devices, particularly silicon devices, are key components of most electronic circuits.
• When the temperature is low, semiconductors act as insulators, but when the temperature is high, they act as conductors.
• The rate of thermal creation of intrinsic carriers reduces as the temperature falls. As a result, the semiconductor begins to behave like an insulator over time.
