摘要：
The problem of current distribution in the integer quantum Hall regime was studied in Hall bar samples of a two-dimensional electron gas (2DEG) by means of an inductive coupling technique. Our results imply that edge states do not carry the total Hall current, injected into the sample. It was found that in the absence of any nearby metallic plates such as gates, the total non-equilibrium Hall current, is carried by 2DEG extended bulk states. (C) 1998 Elsevier Science B.V.
