ABSTRACT

The properties of two-dimensional electron fluids and crystals bound to a bulk helium surface have been studied extensively for the last decade1. These systems are limited to the classical regime due to theinstability of a highly charged surface to fluctuations. The maximum density on a bulk helium surface is 2.4×109 cm−2. At this density the melting temperature ∝ \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$ \sqrt{n} $$\end{document} is ~ 1 K compared to a Fermi energy ∝ n ~ 50 mK. Here n is the electron areal density. The high melting temperature is a result of the large potential energy reduction for the Coulomb interaction in the lattice phase where small electron separations are excluded. More... »
