摘要: Abstract The positive surface charge induced by the photoelectron emission is a major problem in XPS study of insulating materials. This paper devoted to definition an experimental procedure for analysis large gap oxides, three which are considered: sapphire, quartz and yttria-doped-zirconia, their widths being respectively about 8.5, 9 5.5 eV. influence substrate temperature on first described. compensation then studied using low energy electron bombardment (flood gun), was calibrated prior experiments; reliability reproducibility results (peak positions, FWHM intensity) discussed. question Fermi edge referencing materials, as well role potential neutralization conditions its possible use material outlined. last section establishes set technical recommendations insulators, pointing out criteria be chosen optimizing flood gun settings.
