Electrons from valence band rises to conduction band when the temperature is greater than 0 k. Is it True or False?

(a) True

(b) False

This question was posed to me during an interview.

I'd like to ask this question from Electrons and Holes in Semiconductor topic in chapter Conduction in Semiconductors of Electronic Devices & Circuits

Best answer
The correct answer is (a) True

The best explanation: As the temperature rises above 0 k, the electrons gain energy and rises to the conduction band from the valence band.
