Question

. At low temperatures, pure
semiconductors act as an insulators.
Why?​

Answer 1

Answer:

at low temperature pure semiconductors act as an insulators because at low temperature in pure semiconductors.,there is no free electrons and these free electrons is responsible for an insulator ti behaves like a conductor. energy is needed in the form of heat or light to free up electrons in an insulator and hence insulator behaves like semi conductors. that's why at low temperature, pure semiconductors act as an insulators.
