Abstract

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/νe2 to within 5% even when the diverging diagonal resistivity reaches ∼100h/νe2. This implies that both Hall and diagonal conductivities approach zero in the localized regime.
