This effect is usually ascribed to the substrate-induced strain in the solid film, which occurs due to the lattice mismatch and 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 H$_2$ and D$_2$, but also mixtures thereof. The experiments show that triple-point wetting is a rather dominating effect which, in contrast to expectations, persists even if the system parameters are widely varied. This indicates that the present understanding of this effect is incomplete. We present an investigation of the influence of the roughness of the substrate which is expected to be responsible for the dewetting of the solid phase.</dcterms:abstract> <dc:contributor>Sohaili, Masoud</dc:contributor> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T14:50:12Z</dcterms:available> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T14:50:12Z</dc:date> <dc:format>application/pdf</dc:format> <dc:creator>Sohaili, Masoud</dc:creator> <dcterms:title>Wetting Studies of Solid and Liquid Hydrogen Isotope Films</dcterms:title> <dc:rights>deposit-license</dc:rights> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103416863-3868037-7"/> <dcterms:issued>2004</dcterms:issued> </rdf:Description> </rdf:RDF>
