WebWe have analyzed the nanoscale organization of various polymer systems by utilizing high-angle annular dark field scanning transmission electron microscopy (HAADF−STEM). All systems under investigation are purely carbon based; in some cases staining was used for comparison with conventional transmission electron microscopy (CTEM) imaging. WebSpecimen must be thin (<40nm) for most high resolution imaging applications. Samples can be prepared by chemical thinning, ion beam thinning, crushing, etc. Limitations HAADF imaging is only quasi-spectroscopic. The image resolution is not as high as that of HREM images. Thick specimens cause beam broadening and degradation of the spatial ...
Web14 de nov. de 2024 · TEM high-angle annular dark-field (HAADF) images of a single NW implanted using a fluence of 1 × 10 15 at/cm 2 and annealed at 1000 °C are shown in Figure 6. HAADF imaging is sensitive to the atomic number of the material (Z-contrast), thus the dark spots visible in Figure 6 a are signs of thinner sample areas. WebThe structural and chemical details of the t-Sb 2 Te 3 thin film were acquired by the high-angle annular dark field (HAADF) imaging technique on a spherical aberration-corrected scanning transmission microscope (STEM) equipped with an energy-dispersive X-ray (EDX) mapping analysis system.
