Abstract
The growth of gold on top of a n-alkane monolayer, which consists of lamellar assemblies with close-packed flat-lying chains, is observed by using scanning tunneling microscopy. The n-alkane monolayer sustains gold atoms,and penetration of the atoms into the monolayer is inhibited. The molecular conformation is unaffected and the arrangement is only slightly changed upon deposition of the gold atoms. Two-dimensional clusters are grown and a smooth monolayer is finally obtained.

A self-assembled monolayer (SAM) of organic molecules on a solid surface is an intriguing system for studying molecular properties and metal-organic contact, which is essential for molecule-based nano-devices
The isotropic cluster shape makes a striking contrast with the growth of palladium on the Au(111) surface covered with the n-alkane monolayer, which shows a nano-rod aligned along the alkyl chain with its length regulated by the lamellar boundaries [12]

The growth of gold on top of a n-alkane monolayer, which consists of lamellar assemblies with close-packed flat-lying chains, is observed by using scanning tunneling microscopy. The n-alkane monolayer sustains gold atoms, and penetration of the atoms into the monolayer is inhibited. The molecular conformation is unaffected and the arrangement is only slightly changed upon deposition of the gold atoms. Two-dimensional clusters are grown and a smooth monolayer is obtained.
