Figure 11
The valence region of the Pt(111) surface as seen in a time-resolved experiment with the hydrogen gas dose. Each spectrum was taken at approximately one-second intervals, thereby the scan number also indicates the amount of time that has passed since the beginning in seconds. The black lines in (a) indicate the binding energy region that was used for the integrated signal in (b), where the trend of the increase of the signal is shown as a black line. (c) The first and last ten spectra of the measurement in red and black, respectively. The spectrum at the end has been fitted with a Voigt curve to show the appearance of the peaks. All measurements were made at a photon energy of 200 eV. |
