Abstract

The atomic force microscopy (AFM) and scanning tunneling microscopy (STM) images of a monolayer of xanthine molecules adsorbed on graphite were simulated by calculating total and partial electron density plots for a model bilayer of xanthine and graphite. Unlike the case of the total density plots, the partial electron density plots depend strongly on the registry of xanthine molecules on the graphite lattice. This result explains why the STM images show a superstructure modulation, whereas the AFM images do not.
