We present SIMION 8.1 Monte Carlo type simulations of the response function and detection solid angle for long lived Auger states (lifetime τ ∼ 10(-9) - 10(-5) s) recorded by a hemispherical spectrograph with injection lens and position sensitive detector used for high resolution Auger spectroscopy of ion beams. Also included in these simulations for the first time are kinematic effects particu...
A new approach, utilizing an elevated pressure reactor and high-resolution electron energy loss spectroscopy (HREELS), to the measurement of sticking coefficients of methane decomposition on Ru(0001) has been demonstrated. It has been shown that the detection, by Auger electron spectroscopy and photoelectron spectroscopy, of fractional monolayers of carbon on ruthenium is difficult because of t...
Auger Electron Spectroscopy in high vacuum: Nanocharacterisation in the Scanning Electron Microscope
UNLABELLED Pure zinc oxide and zinc oxide/barium carbonate nanoparticles (ZnO-NPs and ZB-NPs) were synthesized by the sol-gel method. The prepared powders were characterized by X-ray diffraction (XRD), ultraviolet-visible (UV-Vis), Auger spectroscopy, and transmission electron microscopy (TEM). The XRD result showed that the ZnO and BaCO3 nanocrystals grow independently. The Auger spectroscopy ...
The short-time dynamics of amorphous beryllium oxide (a-BeO) has been investigated for electronic excitation/ionization by fast incident electrons, as well as by Ar, Ar, Xe, and Xe ions at velocities of 6% to 10% the speed of light. Site specific Augerelectron spectra induced by fast heavy ions are the central point of this investigation. Electron induced Auger spectra serve as a reference and ...
