A semiconductor has electrical properties between metals and insulators but similar to all materials, its resistivity will decrease and will conduct more electricity as its temperature is increased?
A
Correct answer
Explanation
Semiconductors exhibit a negative temperature coefficient of resistance - their resistivity decreases as temperature increases. This is because higher temperature provides more thermal energy, exciting more electrons into the conduction band. This behavior is fundamentally different from metals, whose resistivity increases with temperature due to increased phonon scattering.
