Abstract

Selective eradication is presented as a post-processing technique for as-grown vertically aligned carbon nanotubes (CNTs) for removing unwanted individual nanotubes in order to generate desired patterns. A scanning anode is applied to select a nanotube in a CNT emitter array. Using a saturated emission current, a nanotube emitter can be removed in a controlled way. Vertically aligned single multiwalled carbon nanotubes (MWNTs) are realized using a combination of e-beam lithography and plasma-enhanced chemical vapour deposition (PECVD) growth. The scanning anode is actuated with a 3-DOF nanorobotic manipulator with nanometer resolution inside a scanning electron microscope (SEM). The patterned nanotube array can be applied as patterned emitter arrays for parallel electron-beam-induced deposition, nano imagers or read-only memory (ROM) devices for fixed pattern displaying or recording.
