Using scanning tunneling microscopy observations and density functional theory calculations, regularities of the Al magic cluster array self-assembly on Si(100) surface has been elucidated. While a single Al cluster occupies an area of 4a×3a, an ordered Al-cluster array exhibits a 4×5 periodicity, as the clusters in the array are separated by the 4a×2a “spacers”. The plausible structural model for...
Self-organized formation of Al nanoclusters (i) induced by interaction of atomic hydrogen with the Si(100)c(4×12)-Al surface and (ii) in the course of Al deposition onto the Si(100)c(4×12)-Al surface has been quantitatively characterized using scanning tunneling microscopy measurements of the Al nanocluster number density. The obtained data have been evaluated within the framework of nucleation rate...
