Fig. 4 — a PGNP clusters assembled from 25 nm Au NPs (PS = 6k) with PP/PE at $\emptyset_{PP / PE}$ ~ $0.05 %$ . Scale bar is 200 nm. b TEM image of (1.7k) Au-PS_0.70 NP crystals formed with PP/PE at $\emptyset_{PP / PE}$ ~ $0.08 %$ and Voronoi representation color coded by the Voronoi cell area in 2D. c Crystal size distribution plot, fitted with a normal distribution curve. d Voronoi cell area vs. crystal size in 2D, fitted with a linear curve. (1.7k) Au-PS_0.70 NP crystals characterized in c and d were formed with PP/PE at $\emptyset_{PP / PE}$ ~ $0.08 %$ . e Schematic illustration of the templated carbon films with orthogonally arrayed holes mounted on TEM grids. Two possible nucleation sites are highlighted with blue circles in f. g (1.7k) Au-PS_0.70 NP crystals formed at bridge sites between adjacent holes. h (1.7k) Au-PS_0.70 NP crystals formed at center sites of the hole lattice. PP/PE was added at $\emptyset_{PP / PE} ~ 0.15 %$ . Scale bars are 500 nm in f–h.
