Research paper thumbnail of The alignment of spectrometers and quantitative measurements in X-ray photoelectron spectroscopy

There are two important classes of spectrometer: (i) those in which the analyser acceptance area is independent of the analysed electron kinetic energy; and (ii) those in which this area varies. Model experiments show how an example of a VG ESCALAB II conforms to class (i) whereas an example of an SSI X-probe is of class (ii) and shows an analyser acceptance area which depends approximately inversely on the emitted electron kinetic energy. This latter result means that the SSI X-probe spectrometer must be aligned for the electrons of the highest kinetic energy (smallest analyser acceptance area). A misalignment of 0.1 mm in the sample height can cause a 10% change in the relative intensities between 0 and 1000 eV binding energies. This dependence of the analyser acceptance area with energy is an effect likely to be common in the advanced electron optical systems of modern electron spectrometers and should be understood in order to use such spectrometers effectively. Such dependencies should be determined by analysts for their own instruments in the operating mode that is used for conducting work in which the repeatability of intensity measurements is important.

Research paper thumbnail of Separation of dipole and impact scatterings in high resolution electron energy loss spectroscopy: Experiment from model organic material

Journal of Electron Spectroscopy and Related Phenomena, 1999

The interpretation of High Resolution Electron Energy Loss Spectroscopy (HREELS) spectra recorded... more The interpretation of High Resolution Electron Energy Loss Spectroscopy (HREELS) spectra recorded from polymers remains a difficult task because of (1) the relatively poor resolution achieved on these non-ordered systems, (2) the large number of vibrational features induced by the numerous chemical groups in the monomer unit, (3) the superposition of the dipole, impact and resonant scattering mechanisms. In this report, the study of the physical mechanisms responsible for the electron-molecular vibration coupling is investigated, using a simple model system consisting of a well-ordered film of eicosanoic acid adsorbed on a GeS substrate and an hypothesis supposing that dipole scattering is extinguished in non specular geometry. The ordered character of the molecular layer allowed to separate the dipole from the impact contributions in the signal recorded in specular geometry. The results support the idea that any vibrational mode of an organic compound induced by electron excitation contains both contributions with different relative extent, depending on the chemical nature of the molecular group involved in the vibration and their orientation. Cross section measurements for both interaction mechanisms are in agreement with theoretical prediction, confirming the validity of this new and original method suggested for the separation of the interaction mechanisms. Furthermore, we measured a resonance near 6 eV impact energy as the intensity of the n(C-D) band is enhanced for this impact energy. This observation again is in agreement with our hypothesis that the impact scattering is the dominant interaction mechanism involved in the vibrational excitation of the C-D group. This study allowed for a model of the geometry of adsorption of the molecule on the substrate. It is confirmed that the eicosanoic acid adsorbs the COO group on the substrate, with the long hydrocarbon chain standing up and the CD 3 terminating group pointing out of the surface.
