Adsorption mechanism of aligned single wall carbon nanotubes at well defined metal surfaces
Abstract
In situ dry deposition of individual single wall carbon nanotubes on metal surfaces has been studied by scanning tunneling microscopy. The nanotubes are lying parallel over large areas, with a preferential adsorption along the substrate lattice directions, for which the nanotube-surface interaction is maximized. The authors propose a mechanism for the deposition process, where the aligned geometry results from a selective transfer of the nanotubes depending on their orientation relative to the substrate.
