R. Djulgerova et V. Mihailov, LASER-ASSISTED PHOTOELECTRIC OPTOGALVANIC ANALYSIS OF THIN-FILMS AND SURFACES USING A HOLLOW-CATHODE GLOW-DISCHARGE, Applied physics. B, Photophysics and laser chemistry, 56(5), 1993, pp. 301-305
It is shown that substitution of the spectral line intensity with the
photoelectric optogalvanic signal in the hollow-cathode glow discharge
enhances the ability for layer-by-layer spectral analysis of surfaces
and layers. In particular, this approach improves substantially the t
hin-film thickness measurements and analysis accuracy.
