Figure 3: Systematic tuning of surface wettabilities creates continuous superlattice structural change.

From: Nanoscale surface chemistry directs the tunable assembly of silver octahedra into three two-dimensional plasmonic superlattices

Figure 3

(a) Increase in the bulk water contact angles of a Ag film functionalized with various thiols. Error bars are s.d. of five measurements for each ligand. (b) Using increasingly hydrophobic Ag octahedra for self-assembly gives rise to a continuous superlattice evolution, with the HCP superlattice changing into the OH structure and finally into the square superlattice. All scale bars, 200nm. (c) Schematic illustration of the relationship between the three superlattices.
