Two-Dimensional Magnetotransport in the Extreme Quantum Limit

Abstract
A quantized Hall plateau of ρxy=3he2, accompanied by a minimum in ρxx, was observed at T<5 K in magnetotransport of high-mobility, two-dimensional electrons, when the lowest-energy, spin-polarized Landau level is 13 filled. The formation of a Wigner solid or charge-density-wave state with triangular symmetry is suggested as a possible explanation.
