Abstract

An ac heat-capacity study of CF4 on graphite in the multilayer region is reported. The results indicate that CF4 does not wet graphite between 18 and 80 K. Below 72 K, the thickness of the adsorbed film is limited to two layers. A bilayer-to-trilayer layering transition is observed near 72 K. The heat-capacity signal shows unusual behavior near T which may be related to the surface transition in the CF4 bulk clusters due to the presence of the graphite substrate.
