摘要：

We investigated the integer quantum Hall effect (IQHE) using an inductive method. The following conclusions can be derived from our study: (i) When the Fermi energy is located between Landau levels the only extended states at the Fermi energy are located at the physical edges of the sample. (ii) The extended states located at the bulk of the sample below the Fermi energy are capable of carrying a substantial amount of Hall current, but cannot screen an external electrostatic potential.
