Figure 6.

Side and top views of close-packed monolayers on Au(111): alkanethiol SAM with $(\sqrt{3}\times \sqrt{3})\text{R}30°$ structure (0.33 ML, left), DAM occupying threefold hollow sites (0.40 ML, center), and DAM occupying twofold bridging sites (0.50 ML, right). The dashed ellipses delineate the space available to accommodate molecular cross sections.
