19. Submonolayer coverages of Ag on Pt(111) are known to mix into the topmost Pt layer if grown above or annealed to more than 620 K, providing another efficient way of strain relief in this system (see H. Röder, R. Schuster, H. Brune, K. Kern, Phys. Rev. Lett 71 (1993) 2086). However, as alloying is confined to the first atomic layer, complete demixing into separate phases (or no intermixing at all if coverages greater than 1 ML are annealed) happens as soon as the Ag coverage exceeds 1 ML.
