Thickness measurements by the method of angle-resolved, self-ratio X-r
ay fluorescence spectrometry (AR/SR/XFS) have been carried out on thin
solid films using monochromatized synchrotron radiation at the Bonn s
torage ring ELSA. Synchrotron radiation was monochromatized by means o
f a double-crystal monochromator and fluorescence radiation was detect
ed by a Si(Li) semiconductor detector. The results for sample systems
consisting of Au on Si, Cr on SiO2 and TiO2 on alkali-free glass are v
ery satisfactory and agree well with results obtained by other methods
.
