The atomic force microscope probe (made through micro-fabrication) is very sensitive and is the part that comes in contact with the sample. As the tip moves across the surface of the sample, it senses its contours. As such, it does not rely on electrons or light to view the sample ...
This explanation does not account well for the uniformity of the halo in Figure 3 (b) given the small volume sampled by the electron beam - a cylinder through the foil not much larger than 5 nm in diameter. Alternatively, the halo could arise from an oxide layer on the foil. Although ...
Electron microscope contrast of small atom clustersThe contrast for gold due to single atoms, flat clusters of 3 and 7 atoms and a double layer cluster of 19 atoms is calculated as a function of defocus including the effect of spherical aberration. The exact complex scattering factor is used ...
Through a combination of aberration-corrected high-resolution scanning transmission electron microscopy and three-dimensional atom probe tomography, the tr...

HAADF-STEM images were collected on a JEOL ARM-200 F field-emission transmission electron microscope operating at 200 kV accelerating voltage. ICP-AES (Atomscan Advantage, Thermo Jarrell Ash, USA) was used to determine the concentration of metal species. X-ray diffraction patterns were recorded...
Crewe used a high resolution scanning microscope developed in his laboratory to image thorium and uranium atoms in an organic molecule. In neither case was a conventional electron microscope used.doi:10.1038/234345a0PRESTRIDGE, E. BYATES, D. J. C...
In addition, advanced characterization techniques including scanning tunneling microscope (STM), aberration-corrected high-angle annular dark-field scanning transmission electron microscopy (AC-HAADF-STEM), synchrotron-radiated X-ray absorption fine structure (XAFS) spectroscopy, etc., are widely adopted ...
Phase recovery and lensless imaging by iterative methods in optical, X-ray and electron diffraction Phase plays a similarly fundamental role in matter-wave interferometry, for which the field-emission electron microscope provides ideal instrumentation. The ... JCH Spence,U Weierstall,M Howells - 《...
Atom has symbol view that isn’t shown all the time. CTRL-R brings it up and it uses a search style but you can also scroll through all symbols Atom depends heavily on packages (plugins that anyone may write). The package management is good, and the packages I’ve tried have been sup...
Correlative atom-probe tomography and transmission electron microscope study of a chemical transition in a spinel on an oxidized nickel-based superalloy Complex thermally grown oxides (TGOs) are formed on a single-crystal Ni-based superalloy due to a large fraction of alloying elements. Combining at...
