Abstract

Various phenomena have been successfully analyzed by an edge-channel formulation of integer quantum Hall effect (IQHE) [1–3], which describes the conduction only in terms of the “edge current” that flows along the edge of a two-dimensional electron gas (2DEG) layer. On the other hand, a number of experiments strongly suggest that the conduction is dominated by “bulk Hall current” [4–8]. Consideration is given to an implication of the edge current in this section.
