摘要：
We present a theoretical approach for the integer quantum Hall effect, which is able to describe the inter-plateau transitions as well as the transition to the Hall insulator. We find two regimes (metalliclike and insulatorlike) of the top Landau level, in which the dissipative bulk current appears in different directions. The regimes are separated by a temperature-invariant point. [S0163-1829(98)01447-7].
