Transmission electron energy loss spectroscopy has been applied to rare earth oxides by Colliex et al. (1976b), Cukier et al. (1980), Brown et al. (1984), Colliex et al. (1985) and by Gasgnier and Brown (1986), while the spatial resolution of the electron microscope has been exploited in studying oxide segregation by Dexpert et al. (1980). The main qualitative differences between metal and trivalent oxide EELS spectra in the valence region is the establishment of an energy gap of order 4 e V, and... 

We briefly note that the so-called energy-loss function Im(l/e) which characterizes the response of a solid to incident electrons in, for example, transmission electron energy loss spectroscopy (EELS) has a pronounced maximum for e = 0 and e" ... 

Electron Energy-Loss Spectroscopy in the Transmission Electron Microscope (EELS)... 

Several structural characterisations of carbon nanotubes (CNTs) with the cylindrical graphite are reviewed from the viewpoint of transmission electron microscopy (TEM). Especially, electron energy loss spectroscopy (EELS) by using an energy-fdtered TEM is applied to reveal the dependence of fine structure of EELS on the diameter and the anisotropic features of CNTs. 

The first two advantages listed above allow an optical method like transmission or reflection IR spectroscopy to be used for studies which would be impossible for a widely used competitive technique, electron energy loss spectroscopy (EELS). EELS must... 

Electron energy loss spectroscopy An analytical technique used to characterize the chemistry, bonding, and electronic structure of thin samples of materials. It is normally performed in a transmission electron microscope. The inelastically scattered electron beams are spectroscopically analyzed to give the energy spectrum of electrons after the interaction. 

The hybridization of carbon atoms is the major structural parameter controlling DLC film properties. Electron energy loss spectroscopy (EELS) has been extensively used to probe this structural feature [5. 6]. In a transmission electron microscope, a monoenergetic electron beam is impinged in a very thin sample, being the transmitted electrons analyzed in energy. Figure 27 shows a typical... 

There are two types of electron energy loss spectroscopy currently in use. The first of these is found in scanning transmission electron microscopes. As indicated in Figure 5.1, compositional information may be obtained in the TEM by measuring the energy loss of the inelastically scattered electrons transmitted through a thin specimen.
