    • Considering the statistical uncertainties, one might argue that only three peaks are actually resolved in the STM height histogram: 14 kDa, 22 + 29 + 34 kDa, and 45 + 55 kDa. The excellent correlation with six mass abundance peaks provides further evidence that the nanocrystal preparation results in distinct chemical species, with many fewer nanocrystals between these stable core sizes. Ultimately, the mapping from STM height to nanocrystal core diameter will not be strongly dependent on whether one assumes 3 distinct peaks or more, but these structures allow accurate correlation of the two size measurements and lend confidence that STM height measurements can distinguish the different nanocrystal species.
