NANOSCALE TEMPLATING OF ONE-DIMENSIONAL SURFACE MOLECULAR-STRUCTURES

Scanning tunneling microscopy has been used to demonstrate the formati on of self-assembled one-dimensional ross of C-60 on Au/Ni(110), which is of interest in relation to molecular wire growth. This made use of the [001] direction chain structures formed at Au coverages greater t han 0.4 monolayers to act as adsorption templates, the interchain sepa ration being dictated by the coverage. C-60 molecules adsorb on the Au chain structures forming sinlge molecular rows aligned along the dire ction of the Au chains. The separation or C-60 molecules along [001] i s approximately 10 Angstrom, the same as the bulk intermolecular spaci ng. [S0031-9007(97)05177-6].
