Electronic transport in a 2-dimensional electron gas (2DEG) has been studied widely, in particular following the discovery of the quantum Hall effect (QHE). Initially, the integer effect (IQHE) was explained as to emerge in the full width of the 2DEG area, i.e. as a bulk effect 1. To explain the width of the quantized plateaux, the existence of localised states residing in the bulk was required.
