It implies that in the liquid phase above the triple-point temperature, T3, complete wetting with the formation of arbitrarily thick films is observed, whereas below T3 only a few monolayers of the solid phase are adsorbed at saturated vapour pressure. This effect is usually ascribed to substrate-induced strain in the solid film, which occurs due to lattice mismatch and/or the strong van der Waals pressure in the first monolayers. Molecular hydrogen is a suitable system to investigate this phenomenon, in particular by tailoring the adsorbate-substrate interaction by means of thin preplating layers of other adsorbates, and by introducing disorder into the system by using not only the pure systems H2 and D2, but also mixtures thereof. In particular the dependence of T3 of the mixture on the mass ratio of its components is measured and deviations from the simple van der Waals law are discussed. The experiments show that triple-point wetting is a rather dominating effect, which in contrast to expectation persists even if the system parameters are widely varied, indicating that the present picture of this effect is incomplete.</dcterms:abstract> <dc:contributor>Sohaili, Masoud</dc:contributor> <dcterms:title>Triple-Point Wetting of Molecular Hydrogen on Tailored Substrates</dcterms:title> <dc:creator>Sohaili, Masoud</dc:creator> <dc:creator>Leiderer, Paul</dc:creator> <dcterms:rights rdf:resource="https://creativecommons.org/licenses/by-nc-nd/2.0/legalcode"/> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/4651"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T14:49:17Z</dc:date> <dc:contributor>Leiderer, Paul</dc:contributor> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T14:49:17Z</dcterms:available> <dcterms:bibliographicCitation>First publ. in: Journal of Low Temperature Physics 122 (2001), 3-4, pp. 249-255</dcterms:bibliographicCitation> <dc:language>eng</dc:language> </rdf:Description> </rdf:RDF>
