Liquid-vapor coexistence at a mesoporous substrate.
The condensation of hexane vapor onto a mesoporous Si substrate with a pore radius of 3.5 nm has been studied by means of volumetry and ellipsometry. The filling fraction of the pores and the coverage of the substrate have been determined. The coverage of the regime after the completion of capillary condensation has been compared to recent theoretical work.
