Abstract: Formation of metal clusters on surfaces is of interest for several applications, including electrocatalysis. Tunability of the diffusion characteristics of adatoms on various surfaces holds the promise for controllable growth of metallic nanostructures. Atom clusters on various substrates and their size dependent electronic and magnetic properties have been investigated intensively during the past twenty years. Recent advances in the synthesis of single layer graphene and the understanding of its unique properties have provided a ground for many other two-dimensional materials such as transition metal dichalcogenides (TMDs).

In this talk, I will summarize our recent studies on formation of metal clusters (Pt, Ag, and Au) on graphene, TMD monolayers (MoS2, MoSe2, WS2, and TaS2) and as intercalated in their bilayer heterostructures, based on density functional theory computations:
