Abstract :
Using the electric field penetration technique, the screening by 2DEG in the integral quantum Hall regime was studied. For magnetic fields near the filling factor 2, besides the hopping transport supplying charge into the structure, another new type of mechanism due to the breaking of topology of the 2DEG was identified.
