Static Structure Factor of Two-Dimensional Liquid 3He Adsorbed on Graphite

Static structure factor of two-dimensional liquid 3He adsorbed on graphite

Liquid He is a model system for strongly correlated Fermi liquids. For this reason, many X-ray and neutron scattering experiments have been performed to understand the structure and dynamics of this quantum fluid. We have recently shown that two-dimensional liquid He sustains long-lived zero-sound excitations at large wave-vectors (Nature 483, 576, 2012). Here we show that its static structure ...

Mobility measurements of two kinds of two-dimensional fluids. Methane adsorbed on graphite

2014 The diffusion coefficient of a CH4 submonolayer adsorbed on (0001) graphite is measured as a function of coverage and temperature by quasi-elastic neutron scattering. The experimental data permit us to clearly distinguish two kinds of adsorbed fluids, i.e. a 2D liquid coexisting with a 2D gas and a 2D hypercritical fluid whose density varies continuously with coverage. The mobility disappe...

A first order two-dimensional melting transition : methane adsorbed on (0001) graphite

2014 The variation of long range order of a registered solid submonolayer of methane adsorbed on the graphite basal plane is measured at melting by neutron elastic scattering. The sudden loss of order indicates a first order melting transition and defines the two-dimensional triple point of the layer, namely 56 ± 0.4 K.
