Figure 1
Time evolution and model fits for the reflectivity data. All scans are from the same location except the one from 0 min, which was taken after 500 min at a new site on the same sample that had not been exposed to the X-ray beam during the initial set of experiments. The sharper features of the scan from a pristine area suggest that loss of detail in the time evolution series results from beam damage, not from any natural aging process at the interface. |
