16. A10 and A12 are miscible when coadsorbed, and they form randomly intermixed monolayers. However, vapor annealing selectively places the vapor-phase A12 molecules in the host A10 film, forming discrete domains.

19. Surface coverages were determined using the area under Gaussian peaks that were fit to the distribution of heights for each terrace.
20. Here, the hexagonal lattice is best resolved in the A12 domain, and the c(4 x 2) superlattice is best resolved in the A10 domain, visible as periodic rows.
21. Features with high aspect ratios (such as inserted molecules) cannot be fully resolved with the STM tip and produce image features that are inverted images of the tip. Thus, the apparent width of inserted molecules is much larger than the actual width, obscuring the nearby matrix. Because of the general continuity of the vapor annealing domains, we infer that the domain of A12 continues adjacent to and surrounds the inserted molecule.
