Theoretical studies so far on piezoelectric scattering have resulted in a mobility behaviour of mu similar to T--1/2 in which mu continues to fall indefinitely with increasing temperature T. Such a behaviour cannot tell us where this scattering will become unimportant, as might be expected on physical grounds, The correct behaviour should be a falling curve first, followed by a gradually increasing one when the scattering ceases to be effective. In this work, by using the force-force correlation function technique within the linear response formalism, we obtained a mu versus T curve that shows just this behaviour.
