Abstract
Properties of monomolecular films physisorbed on graphite and boron nitride are generally similar in comparable temperature ranges, except for krypton: the incipient triple point and the commensurate-incommensurate 2D solid transition which occur on graphite do not appear on boron nitride. These discrepancies are shown not to be ascribable to the differences in superficial homogeneity of the various samples used. They certainly reflect the properties of the films on perfect (0001) uniform faces of graphite and boron nitride. The adsorption potentials and thermodynamical data are compared for films giving rise to phase transitions which were studied on both substrates. The differences in the krypton film properties probably originate in the particular size of krypton with respect to the distances between potential wells on both substrates. In this case, the differences in adsorption potentials would be sufficient to result in a drastic change in the nature of the transitions.
