The adhesion of long, straight, single-walled carbon nanotubes to surfaces is examined usingmultidimensional force spectroscopy.\nWe observed characteristic signatures in the deflection and frequency response of the cantilever indicative of nanotube buckling\nand slip-stickmotion as a result of compression and subsequent adhesion and peeling of the nanotube fromthe surface.The spring\nconstant and the elastic modulus of the SWNT were estimated from the frequency shifts under tension. Using elastica modeling\nfor postbuckled columns, we have determined the static coefficient of friction for the SWNT on alkanethiol-modified gold surfaces\nand showed that it varies with the identity of the monolayer terminal group.
