Evidence for a Liquid-to-Crystal Phase Transition in a Classical, Two-Dimensional Sheet of Electrons
Abstract
Experimental evidence is presented for an electron-liquid to electron-crystal phase transition in a sheet of electrons on a liquid-He surface. The phase transition has been studied for electron areal densities from 3\ifmmode\times\else\texttimes\fi{}${10}^{8}$ ${\mathrm{cm}}^{\ensuremath{-}2}$ to 9\ifmmode\times\else\texttimes\fi{}${10}^{8}$ ${\mathrm{cm}}^{\ensuremath{-}2}$ and has yielded melting temperatures between 0.35 and 0.65 K. The phase transition occurs at $\ensuremath{\Gamma}=137\ifmmode\pm\else\textpm\fi{}15$, where $\ensuremath{\Gamma}$ is a measure of the ratio of potential energy to kinetic energy per electron.

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.
