Spinning Carbon Nanotube Nanothread under a Scanning Electron Microscope

Spinning Carbon Nanotube Nanothread under a Scanning Electron Microscope

Nanothread with a diameter as small as one hundred nanometers was manufactured under a scanning electron microscope. Made directly from carbon nanotubes, and inheriting their superior electrical and mechanical properties, nanothread may be the world's smallest man-made fiber. The smallest thread that can be spun using a bench-top spinning machine is about 5 microns in diameter. Nanothread is a ...

Carbon Nanotube Detection by Scanning Electron Microscopy

This study describes an approach towards the detection of carbon nanotubes in scanning electron microscopic images. It is designed to work in a real-time environment for automated nanofabrication. Main difficulties are the high level of image noise and the occurrence of debris objects. A descriptor derived from the principle component analysis of the geometrical object distribution is found to ...

the scanning electron microscope

it is only thirteen years since the scanning electron microscope has been available commercially. yet, even in this short period of time, this instrument has been a powerful tool in the investigation of topography, electrical and magnetic properties, crystal structure, cathodoluminescent characteristics etc. of solid specimens. today, this type of microscope has opened its place alongside the c...

Study of Carbon Nanotube Based Devices Using Scanning Probe Microscope

The Scanning Confocal Electron Microscope

The Scanning Confocal Electron Microscope, is an instrument which permits the observation and characterization of sub-surface structures of thick, optically opaque materials at nanometer level resolutions. The instrument merges the capabilities of the scanning, transmission and x-ray microscopes, and achieves unprecedented resolutions in optically dense materials, by implementing the technology...
