Quantum Hall Effect
... Since the Hall voltage is being held constant,the fact that the current does not change as the magnetic eld is varied implies that the Hall resistance also remains constant. Whenever the Fermi level is in the sub-band of localized states, then, the Hall Resistance remains the same even when the mag ...
