Mobility-
$
\mu=\frac{v_d}{E}
$
$\mu-$ Mobility
$v_d$-Drift velocity
Relation between conductivity and Mobility:
$
\sigma=\mu n e
$
Where n is the number of electrons per unit volume, e is the charge of the electron and $\sigma$ is the conductivity.
In case of a conductor conductivity decrease with the increase of temperature and in the case of semiconductor conductivity increase with increase in temperature.
