| Abstract: | The drift current flowing perpendicular to an applied electric field is calculated. The system consists of a confined two-dimensional electron gas in a normal magnetic field. It is shown that the drift current depends strongly on how the electric potential changes as a function of the position. It is concluded that a theory of the Hall potential including electron interactions is needed. |
