Regular Arrays of Pt Clusters on Alumina: A New Superstructure on Al${}_2$O${}_3$/Ni${}_3$Al (111)

Georges Sitja, Aude Bailly, Maurizio de Santis +2

Alumina ultrathin films obtained by high temperature oxidation of a Ni${}_3$Al (111) surface are a good template to grow regular arrays of metal clusters. Up to now two hexagonal org…
