2-Dim Helium Honeycombs Lattices
One might have thought that only carbon with it's stable sp2 bonds is the only way to get a honeycomb lattice. Observations dating back to 1934 show otherwise. Helium is more like carbon than people generally believe. Aren't self organizing crystals wonderful? I save this abstract to remind myself to buy the article if I am ever rich enough. One pays taxes all ones life, but cannot even read the fruit of the research one is paying for.

Evidence for a Liquid-to-Crystal Phase Transition in a Classical, Two-Dimensional Sheet of Electrons
Received 17 January 1979; published in the issue dated 19 March 1979
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 3×108cm-2to 9×108cm-2and has yielded melting temperatures between 0.35 and 0.65 K. The phase transition occurs atΓ=137±15, whereΓis a measure of the ratio of potential energy to kinetic energy per electron.
