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× to 9× and has yielded melting temperatures between 0.35 and 0.65 K. The phase transition occurs at , where is a measure of the ratio of potential energy to kinetic energy per electron.
