Pseudopartial Wetting and Precursor Film Growth in Immiscible Metal Systems

“…Auger analysis of the Pb−Bi drops yielded drop surface compositions of 22 and 24 atom % Bi at temperatures of 373 and 463 K, respectively. This rather weak segregation of Bi to the surfaces of dilute Pb−Bi alloys, to produce a surface enrichment by about a factor of 2, is consistent with previous observations …”

Wetting of decagonal Al13Co4and cubic AlCo thin films by liquid Pb

“…An suitable method for studying the wetting of oxidizable surfaces is the dewetting of thin (~100nm) slabs [6]. First, the films of Al-Co compounds are prepared (as explained below [7]) in an ultra high vacuum deposition chamber.…”

Analysis of Pseudopartial and Partial Wetting of Various Substrates by Lead

“…In this series of experiments, − substrates in an ultrahigh vacuum (UHV) system were cleaned with an ion gun and a continuous film hundreds of nanometers thick of Pb was deposited by evaporation. We briefly review the procedure used in these experiments.…”

“…Here, we examine experiments where the same single-component material, lead, wets six different surfaces, some exhibiting partial wetting and some pseudopartial wetting. − As an example of a pseudopartial wetting, Figure shows lead drops on Cu(111) with a growing thin film. At later times, the film covers the substrate and equilibrium pseudopartial wetting is achieved.…”
