FIG. 1.

(Color online) The main panel shows and as a function of the magnetic field for temperatures from 22 (red trace) to 1300 mK (yellow trace), for sample 5. The inset (a) shows the schematic diagram of the samples. The substrate is semi-insulating InP. The inset (b) illustrate how we extract the amplitude of the SdH oscillations as a function of , at 1300 mK. Finally, we plot the amplitude in a Dingle plot (c) to obtain the scattering quantum time .

FIG. 2.

(Color online) The density of the 2DEG is plotted for the different samples. Lines are guides to the eye. We used as the best fit to the experimental data for the different samples.

FIG. 3.

(Color online) The dependence of the quantum (triangles) and transport (circles) scattering rates with the distance of the doping layer to the quantum well . The insets shows the dependence of with (a) the amount of doping and (b) the temperature for the case of .
