In the N1s region, deposition of 3.6 ML Li leads to a slight up-shift in BE of the BMP-related peak at 403.3 eV by about 0.5 eV. It also loses most of its intensity, indicating almost complete decomposition of the BMP cations. This seems to be different from the monolayer situation (Figure ), where Li post-deposition caused a much smaller loss of BMP-related N1s intensity.
