What Charge carriers in semiconductors means in Combined Science GCSE, as defined for AQA.
Definition of Charge carriers in semiconductors
Check what you remember
Read the wording for your board, then hide it and explain Charge carriers in semiconductors in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
At low temperatures few charge carriers are available, so resistance is high; at higher temperatures more charge carriers are released, so resistance falls.
