With the rise of temperature, the conductivity of a pure semi-conductor:

Explanation

With the rise in temperature, the conductivity of a pure semiconductor generally increases.Intrinsic semiconductors, those without any intentional doping, exhibit increased conductivity with rising temperature due to the increased thermal energy. As the temperature rises, more electrons in the valence band gain enough energy to jump to the conduction band, creating additional charge carriers (free electrons and holes), thereby increasing the conductivity of the semiconductor material.This behavior contrasts with conductors, where increasing temperature typically leads to a slight decrease in conductivity due to increased collisions among the charge carriers.
