Single-walled carbon nanotube (SWNT) probe microscopy tips were grown by a
surface growth chemical vapor deposition method. Tips consisting of individ
ual SWNTs (1.5-4 nm in diameter) and SWNT bundles (4-12 nm in diameter) hav
e been prepared by design through variations in the catalyst and growth con
ditions. In addition to high-resolution imaging, these tips have been used
to fabricate SWNT nanostructures by spatially controlled deposition of spec
ific length segments of the nanotube tips. (C) 2000 American Institute of P
