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 ...
متن کاملCryo field emission scanning electron microscopy.
Low-temperature scanning electron microscopy (cryoSEM) was introduced in the early 1970s, shortly after the appearance of the first commercial scanning electron microscopes. This technique has been utilized widely in plant biology, the food and paper industry, X-ray analytical studies, and material sciences (8). Major advantages of cryoSEM include being able to avoid deleterious changes associa...
متن کاملNano-structural Characterization of Post-annealed ZnO Thin Films by X-ray Diffraction and Field Emission Scanning Electron Microscopy
ZnO thin films were deposited on Si(400) substrates by e-beam evaporation technique, and then post-annealed at different annealing temperatures (200-800°C). Dependence of the crystallographic structure, nano-strain, chemical composition and surface physical Morphology of these layers on annealing temperature were studied. The crystallographic structure of films was studied using X-Ray Diffracti...

متن کاملField Emission Microscopy, Spectroscopy,Scanning Electron Microscopy and Field Emission Phenomena from Graphene-like Structures
The presented paper gives a general overview of studies of field emission from carbon nanoclusters. The special attention has been given to the study of emission processes in the strong and super strong electric fields from graphene-like structures. The direct experiments have confirmed the phenomena of the low threshold field emission and explosive emission from carbon nanoclusters. Experiment...
