Zero electron kinetic energy spectroscopy of Au , -
Zero electron kinetic energy (ZEKE) spectroscopy and photodetachment cross section measurements have been carried out on Au;. The transition frequencies of ZEKE, peaks and resonance peaks are nearly identical, consistent with the proposal that the excited negative ion of Au, has a geometry quite similar to that of neutral Auh, and supporting the pic.ture of the resonances as weakly bound “surfa...
متن کاملElectron energy-loss spectroscopy in the TEM
Electron energy-loss spectroscopy (EELS) is an analytical technique that measures the change in kinetic energy of electrons after they have interacted with a specimen. When carried out in a modern transmission electron microscope, EELS is capable of giving structural and chemical information about a solid, with a spatial resolution down to the atomic level in favourable cases. The energy resolu...
متن کاملFundamentals of electron energy-loss spectroscopy
Electron energy-loss spectroscopy (EELS) is an analytical technique that is based on inelastic scattering of fast electrons in a thin specimen. In a transmission electron microscope (TEM) it can provide structural and chemical information about a specimen, even down to atomic resolution. This review provides an overview of the physical basis and new developments and applications of EELS in scan...
متن کاملImage simulation for electron energy loss spectroscopy.
Aberration correction of the probe forming optics of the scanning transmission electron microscope has allowed the probe-forming aperture to be increased in size, resulting in probes of the order of 1 A in diameter. The next generation of correctors promise even smaller probes. Improved spectrometer optics also offers the possibility of larger electron energy loss spectrometry detectors. The lo...
متن کاملHigh-energy-resolution monochromator for aberration-corrected scanning transmission electron microscopy/electron energy-loss spectroscopy.
An all-magnetic monochromator/spectrometer system for sub-30 meV energy-resolution electron energy-loss spectroscopy in the scanning transmission electron microscope is described. It will link the energy being selected by the monochromator to the energy being analysed by the spectrometer, without resorting to decelerating the electron beam. This will allow it to attain spectral energy stability...
