Definition of Charge-carrier release in semiconductors
Check what you remember
Read the wording for your board, then hide it and explain Charge-carrier release in semiconductors in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Increasing temperature releases more charge carriers (electrons and holes) across the small energy gap, so the number density n rises sharply.
