Definition of Semiconductor charge-carrier model
Check what you remember
Read the wording for your board, then hide it and explain Semiconductor charge-carrier model in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
The explanation that heating releases many more charge carriers, so the number density n increases and resistance falls.
