Electron microscopy Backscattered

BSE Backscattered scanning electron microscopy. Backscattered electrons are the result of elastic collisions between energetic beam electrons and atoms within the target, for example athin-section. 

FIG. 16 Scanning electron microscopy backscattered electron image showing Auo.5Nio.5Sn4 and Ni3Sn4 at a Pb-Sn solder/Ni interface. The sample was annealed for 150 hr at a temperature of 150 °C. (From Ref. 34.)... 

As NRA is sensitive only to the nuclei present in the sample, it does not provide information on chemical bonding or microscopic structure. Hence, it is often used in conjunction with other techniques that do provide such information, such as ESCA, optical absorption. Auger, or electron microscopy. As NRA is used to detect mainly light nuclei, it complements another accelerator-based ion-beam technique, Rutherford backscattering (RBS), which is more sensitive to heavy nuclei than to light nuclei. 

The samples were characterized by using X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, 57Fe Mossbauer spectroscopy [2] and Rutherford backscattering spectrometry (RBS).

In transmission electron microscopy (TEM), a beam of highly focused and highly energetic electrons is directed toward a thin sample (< 200 nm) which might be prepared from solution as thin film (often cast on water) or by cryocutting of a solid sample. The incident electrons interact with the atoms in the sample, producing characteristic radiation. Information is obtained from both deflected and nondeflected transmitted electrons, backscattered and secondary electrons, and emitted photons.

The phase composition from the surface to the interior of the samples was determined by X-ray diffractometry (XRD) through successive grinding of the surface at 100 pm intervals. The microstructural characterization of the sintered specimens was achieved by scanning electron microscopy (SEM) in backscattered mode. The hardness change from the surface to the interior of the sample was measured by the Vickers indentation method at 19.6 N load. 

Indeed, refined experiments carried out using modem methods of investigation including various kinds of electron microscopy, X-ray diffraction, Rutherford backscattering of light ions, electron probe microanalysis, ion mass spectrometry, etc., showed the layers of chemical compounds, a few nanometers thick, to possess all the properties of bulk phases. For example, in the nickel-aluminium reaction couple R.J. Tarento... 

Figures 5 (a) and (b) show electron micrographs of the RuxSey particles in powder form, Fig. 5.5(a) and in colloidal form, Fig. 5.5(b). The generated particle size in both cases is ca.2 nm. It is, however, interesting that the colloidal route delivers particles with a narrow size distribution. After multiple analysis by EDX performed with transmission electron microscopy (TEM), and/or via Rut-herford backscattering spectroscopy (RBS) we concluded that the stoichiometry of the RuxSey compound corresponds to x 2 and y 1. This is another experimental evidence that the "real" chemical precursor is the intermediate...

Surface analytical methods — Important ex situ methods for surface analysis are X-Ray Photoelectron Spectroscopy (XPS) UV-Photoelectron Spectroscopy (UPS), Auger Electron Spectroscopy (AES), Ion Scattering Spectroscopy (ISS), Rutherford Backscattering (RBS), Secondary Ion Mass Spectroscopy (SIMS), Scanning Electron Microscopy (SEM), Electron Microprobe Analysis (EMA), Low Energy Electron Diffraction (LEED), and High Energy Electron Diffraction (RHEED).
