Özet:

 

A new method which separates phonon scattering from  extrinsic scattering in 2D gases in GaAs is presented.  In contrast to  previous ones, the technique makes no assumptions about the  temperature dependence of the extrinsic scattering.  The preliminary  measurements of the phonon limited mobility mph on two electron  gas samples show a Bloch-Grüneisen regime in the temperature range  1.2-4.5K and the results agree reasonably well with other experimental  and theoretical work.
