Scanning electron microscopy is able to form images of patterns of self-assembled monolayers (SAMs) of alkanethiolates adsorbed on gold. The contrast in these images is unexpectedly sensitive to the structures of the components of the SAMs. Several factors contribute to the contrast: the compositions of the SAMs; the compositions and quantities of adsorbates (both adventitious and intentional) on the SAMs; electron-beam-induced processes involving the SAMs and these adsorbates.
