Fullerene nanowires on a vicinal gold surface — •Néel Nicolas, Kröger Jörg, and Berndt Richard — Institut für Experimentelle und Angewandte Physik, CAU Kiel
Submonolayer coverages of fullerene molecules on vicinal gold surface were investigated by low-temperature scanning tunneling microscopy. Straight fullerene stripes of few nanometers width and extending over hundreds of nanometers have been fabricated on the gold surface by utilizing faceting of Au(433) substrates upon C60 adsorption and subsequent annealing. The observed step bunching is attributed to a lowering of the facet free energy. This surface morphology is a promising template candidate for subsequent deposition of functional units.
