Universality of the Hall effect in a magnetic-field-localized two-dimensional electron system

We report Hall effect measurements of the localized two-dimensional electron system at low Landau level filling factors {ν}, including the same regime previously identified as a pinned Wigner crystal. We find that the Hall resistivity is universally given by the classical, free-electron gas value of h/{ν}e² to within 5% even when the diverging diagonal resistivity reaches {~}100h/{ν}e². This implies that both Hall and diagonal conductivities approach zero in the localized regime.
