We study quantum transport properties of two dimensional electron gases in Hall regime. We determine the total current I from the bulk Green function. This quantum -mechanical property is an exact result that holds as long as the high-field expansion is applicable. We study the dependence of the plateau width on temperature or disorder broadening. We have numerically computed the Hall conductance including the self consistent equation which is independent of the magnetic field.
