Carbon nanotubes as tips in non-contact SFM
The demand for sharp and stable tips suggests the use of carbon nanotubes as probing tips in scanning force microscopy. Here, we report a comparison of the long-range forces of conventional tips and nanotube tips, topographical images of various surfaces, such as Cu(lll), Si(111)7 X 7 and NaCl(100), as well as images of a bundle of multiwalled nanotubes, which was deposited by severe tip crashing. It is found that the long-range forces of carbon nanotube probing tips are reduced and that they are more resistant to wear than conventional silicon tips
