The resistivity of an intrinsic semiconductor decreases with increasing temperature. This is because with increasing temperature,
AnswerClick to flip back
A
The carrier concentration increases but the mobility of carriers decreases
💡 Explanation:
Conductivity is inversely proportional to resistivity. As we increase the temperature in intrinsic semiconductor, both electrons and holes start vibrating and colliding with each other generating more and more electrons and holes. Due to collision between the atoms, mobility decreases.
