Keywords : quantum well * quantum Hall effect * heterodimensinal junctions * magnetocapacitance measurement
Subject RIV: BM - Solid Matter Physics ; Magnetism

Results obtained by the electric field penetration method are analysed. In the integral quantum Hall effect regime a topological phase transition takes place which is due to the intrinsic disorder of dopants in the source layer in the vicinity of the quantum well.
