Beschreibungen/Notizen

• The multiwalled carbon nanotubes (MWCNTs) fabricated in a fast-heating chemical vapor deposition process were stretched using a microprobe system in a scanning electron microscope. The clean and straight MWCNTs survived multiple telescoping extension and eventually evolved into a gradually sharpened configuration. Some of the so-made telescopic MWCNTs were fabricated into atomic force microscopy probes. Their slender shape enabled them to image the deep holes on an anodic aluminum oxide template surface well. Also, their telescopic structure helped avoid mechanical instability and yield a good amplitude response curve.
