Consequences of an exceedingly strong electric field (E field) on the groundstate energetics and transport properties of a 2D spinless electron gas in aperpendicular magnetic field (a Quantum Hall Effect (QHE) configuration) areinvestigated to all orders in the fields. For a conventional semiconductor, wefind fractional values of the Hall conductivity and some magnetoelectriccoefficients for certain values of E and B fields that do not result frominteractions or impurities, but are a pure consequence of a strong enoughin-plane E field. We also determine analytically the ground state energy, andresponse properties such as magnetization and polarization as functions of theelectromagnetic field in the strong E field limit. In the case of Graphene, weobtain more complex behaviors leading to the possibility of irrational Hallvalues. The results are also qualitatively discussed in connection to variousmechanisms for the QHE-breakdown.
