VY 30 20 10 ML 10 + +++ 0 2000 25 ML) Intensity (kHz) 101 0 + • 60 ML 20 10L + OL 0 200 400 600 800 1000 Temperature (K) The picture shows the Au (-) and W(+) XPS intensity for 10, 25 and 60 Au ML on W. The temperature Tis increased leading to changes in the intensities of these peaks. a) An Al X-ray source with a photon energy of 1465 ev was used. What XPS lines could be measured with these lines/ Which do you expect were actually used? b) How should the intensity change around 700K be interpreted?
