摘要
The depth resolutions achieved by time-of-flight secondary ion mass spectrometry (TOF-SIMS) and glow discharge optical emission spectroscopy (GD-OES) are comparable for the analysis of relatively flat specimens. However, the precision of sputtering-induced depth profiling techniques has been shown to be dramatically influenced by the initial roughness of specimen surface. The effect of the specimen roughness on the depth resolution achieved by both techniques has been examined here using textured aluminium substrates supporting anodic oxide films. As a result of dissimilarities in the sputtering processes, TOF-SIMS and GD-OES show significantly different elemental depth profiles for electrolyte-derived species incorporated into anodic oxide films formed on superpure aluminium substrates of controlled texture.
