摘要：

Thermodynamic and structural characterizations of krypton adsorption at 79 K on (0001) graphite preplated with carbon tetrachloride (CCl4) have been performed by means of classical volumetric measurements and X-ray diffraction. Krypton condensation results in the compression and partial displacement of the preadsorbed CCl4 film, and in the growth of three-dimensional CCl4, crystallites. When less than one CCl4 monolayer is preadsorbed, krypton adsorption occurs preferentially on the bare part of graphite and the krypton two-dimensional solid undergoes a commensurate-incommensurate transition before CCl4 displacement. There is no significant indication for the formation of a two-dimensional (krypton-CCl4) solid solution.
