New fractional quantum Hall state in double-layer two-dimensional electron systems

Eisenstein, J. P., Boebinger, G. S., Pfeiffer, L. N., West, K. W., He, Song·1992·Physical Review Letters

Abstract

Transport studies on bilayer two-dimensional electron systems in GaAs double quantum wells have revealed a new fractional quantum Hall state that has no known counterpart in a single-layer 2D system. At total filling fraction \ensuremath{\nu}=1/2 we observe a deep minimum in the diagonal resistivity and a flat Hall plateau within 1.5% of 2h/${\mathit{e}}^{2}$. Studies of this new state in several samples with varying densities and layer separations strongly suggest this new state arises from interlayer Coulomb correlations. The data also suggest that the \ensuremath{\nu}=1 quantum Hall effect seen in these samples has a similar origin.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
