Conductivity of semiconductors depends strongly on temp why

Answer»

Explanation:

For semiconductors the electrons in it aren't as tightly bound to the atoms as in nonconductors but they aren't too loose as in conductors either...

The conductivity of a material largely depends on the NUMBER of free electrons (the flow of ELECTRICITY is taken in opposite direction to the flow of electrons or the negative charges) when temperature is increased the electrons gain ENERGY and the number of free electrons increases exponentially thus conductivity increases with INCREASING temperature.... when temperature is decreased the electrons loose energy and they get back in orbits of the atoms thus the number of free electrons decreases and with it conductivity decreases too..
