Extensive study using X-ray diffractometry, SEM and TEM revealed that scales formed on the Al-deposited foils transform from γ- to θ- to α-Al_2O_3 with definite stages in a TTT type diagram. As the oxidation temperature rises, each transformation completes ...

SEM image of the nanorings among the etching products (Fig. 1d and e). The schematic diagram, drawn by Vesta [42], illustrates the morphology of a hematite crystal composed of {113}, {104} and internal {102} planes (Fig. 5). The morphology of hollow bipyramid and nanorings agrees ...
A systematic investi- gation has established that the ion beam influences CL emission of diamond, with a dependency on both the ion beam and electron beam acceleration voltage. They showed that CL imaging can be man- ually combined with FIB-SEM tomography with a modified protocol for 3D ...
1. A process for preparing a site specific ultra-thin sample lamella with a focused ion beam and scanning electron microscope (FIB-SEM) dual-beam system including one or more electronic controllers and tangible, non-transitory computer readable memory coupled to the one or more electronic controlle...
In a direct comparison of AFM, SEM, scanning near-field optical microscopy (SNOM) and transmission electron microscopy (TEM), Grabar et al. demonstrated that TEM is a preferred method for quantifying the size, shape, and spacing of nanoparticles in nanoparticle arrays due to high lateral ...
