Abstract EN
Self-assembled monolayers (SAMs) of decanethiol (C10) on Au (111) substrate, prepared at room and elevated temperatures, were studied using scanning tunneling microscopy (STM).
Preparation at elevated temperature results in highly-ordered layers with large ordered domains spreading on gold surface with dimensions easily exceeding 25 × 25 nm2.
At room and 313 K of temperatures, the oblique (√3 × √3) R30° structure was observed, whereas, at 333 K the superstructure (4√3 × 2√3) R30° was covering the gold substrate with four molecules per unit cell.
The high-quality of STM results enables us to resolve four symmetry-inequivalent C10 molecules per 10 Å × 8.6 Å unit cell.
The dissimilarity in topographic heights of C10 molecules on Au (111( was attributed to the binding of sulfur headgroup moiety of C10 molecules with different adsorption sites on Au (111).
