Interaction-induced light scattering in thin neon film confined between graphite slabs: MD study

The dynamics of ultrathin neon layer located between parallel graphite walls have been investigated by the classical molecular dynamics simulations. The interaction-induced Rayleigh light scattering spectra of neon layer and the corresponding many-body correlation functions for three layer's thicknesses have been calculated. The calculations have been performed at the constant temperature and for the constant number of neon atoms. The mean square displacement and diffusion coefficient of neon atom in the confined space has been also calculated and discussed. The substantial dependence of the interaction-induced light scattering correlation functions on the separation distance between graphite walls has been observed. Moreover, the structural features of the thin layer have been studied by calculating the neon density profile, perpendicular to the graphite walls. In the innermost region of confined neon layer the increase mobility of neon atoms has been observed.
