Experimental Observation of Crystal-Liquid Coexistence in Slit-Confined Nonpolar Fluids

Forskningsoutput: TidskriftsbidragLetter

Abstract

Films of carbon tetrachloride (CCl 4 ) confined in slit geometry between two flat diamond substrates down to a few tens of Angstroms are studied by combining X-ray reflectivity with in-plane and out-of-plane X-ray scattering. The confined films form a heterogeneous structure with coexisting regions of liquid and crystalline phases. The liquid phase shows short-range ordering normal to the surfaces of the substrates. The experiments directly show the ability of the confinement to induce crystal objects, which is a long-discussed issue in the literature. The surface structure and morphology of the substrates may influence the actual realization of the crystalline phase in confinement.
