(a) Representative XPS spectra for SrTiO₃ crystals with increasing amounts of SrO coverage normalized to the O^1s peak intensity. The Ti^2p and Sr^3d peaks have the same shape and binding energy for each sample, indicating the absence of a second phase. Insets: Zoom-in on the peaks for films with 0, 4 and 8 pulses of SrO. (b) Measured cation ratios (data points) as a function of the photoemission angle and fits (solid lines) according to equation (7). (c) SrO coverage extracted from the fits in (b).
