How do you with a simple model explain the temperature dependence of the(adsbygoogle = window.adsbygoogle || []).push({});

electrical conductivity.

If you use the Drude model you get for the electrical conductivity

sigma = ne^2t / m

where n is the density of mobile electrons and t is the relaxation time.

t is the time between collisions and must be the only variabel here that depends on temperature. How can you estimate t(T).

Maybe there is a better model that describes the temperature dependence of the electrical conductivity.
