High Resolution Image with Multi-wall Carbon Nanotube Atomic Force Microscopy Tip (RESEARCH NOTE)
In this paper, a simple and reproducible approach for attaching the multi-wall carbon nanotubes (MWNTs) to the apex of the atomic force microscope probe has been proposed. For this purpose, the dielectrophoresis method was applied due to its simple performance, cheapness and reliability. In this method, various parameters such as voltage, frequency, concentration of carbon nanotubes solution an...
متن کاملSingle-walled carbon nanotube probes for high-resolution nanostructure imaging
Single-walled carbon nanotube ~SWNT! tips have been used to image nanostructures with high resolution. Studies of gold nanocrystal standards showed that SWNT tips provide a significant improvement in lateral resolution with respect to multi-walled nanotube tips and microfabricated Si tips. The nanotube tips were also used to resolve substructure within SWNTs deposited on surfaces. These results...
متن کاملAtomic resolution imaging of a carbon nanotube from diffraction intensities.
Atomic imaging of three-dimensional structures has required a crystal in diffraction or a lens in electron imaging. Whereas diffraction achieves very high resolution by averaging over many cells, imaging gives localized structural information, such as the position of a single dopant atom. However, lens aberrations limit electron imaging resolution to about 1 angstrom. Resolution is reduced furt...
متن کاملContact transparency of nanotube-molecule-nanotube junctions.
The transparency of contacts between conjugated molecules and metallic single-walled carbon nanotubes is investigated using a single-particle Green's function method which combines a Landauer approach with ab initio density functional theory. We find that the overall conjugation required for good contact transparency is broken by connecting through a six-member ring on the tube. Full conjugatio...
متن کاملSuperaligned carbon nanotube grid for high resolution transmission electron microscopy of nanomaterials.
Nano is one of the hottest topics in current science and technology. Characterizations of nanomaterials by high resolution transmission electron microscopy (TEM) are becoming indispensable today. To gain better performance of TEM, people are expecting a novel TEM grid of which the supporting film should be highly conductive, ultrathin but robust, and preferably nanoholey. Here we report a metho...
