Structure assembly regularities in vapour-deposited gold-fullerene mixture films.

Self-assembly is an attractive phenomenon that, with proper handling, can enable the production of sophisticated hybrid nanostructures with sub-nm-scale precision. The importance of this phenomenon is particularly notable in the fabrication of metal-organic nanomaterials as promising substances for spintronic devices. The exploitation of self-assembly in nanofabrication requires a comprehension of atomic processes creating hybrid nanostructures. Here, we focus on the self-assembly processes in the vapour-deposited Au C mixture films, revealing the exciting quantum plasmon effects. Through a systematic characterization of the Au C films carried out using structure-sensitive techniques, we have established correlations between the film nanostructure and the Au concentration, . The analysis of these correlations designates the Au intercalation into the C lattice and the Au clustering as the basic processes of the nanostructure self-assembly in the mixture films, the efficiency of which strongly depends on . The evaluation of this dependence for the Au C composite nanostructures formed in a certain composition interval allows us to control the size of the Au clusters and the intercluster spacing by adjusting the Au concentration only. This study represents the self-assembled Au C mixtures as quantum materials with electronic functions tuneable by the Au concentration in the depositing mixture.
