    • The resistance of the Ohmic contacts showed to be slightly nonlinear. It is measured independently at Vg= 0 V, where varied within 2.9+- 0.4 kOMEGA over the current range and is subtracted from the measured data. The formation of the constriction at Vg= - 0.6 V gives rise to a series resistance R2DEG from the two wide 2D EG regions, due to the change in geometry. R2D~EG ( = 980 Ω ) has been obtained from the difference of the measured and quantized value of the first plateau and is taken constant for all I - V curves.
