Why does the electrical conductivity

Question:

Why does the electrical conductivity of semiconductors increase with a rise in temperature?

Solution:

The energy gap between the valence band and conduction band is small, at room temperature they do not conduct electricity but raised the electrons to get enough

amount of energy to excite from valence band to conduction band. This is called thermodynamic conduction in intrinsic semiconductors
