All samples were created with identical deposition durations and crucible temperatures, with the only variation being in substrate temperature during deposition. a, c, e Large-scale and b, d, f small-scale scans of polymer assemblies from depositions performed at 22, 100, and 180 °C substrate temperatures, respectively. The green circle in b indicates a bright spot due to iodine that remains on the surface. Scan parameters: a -1.95 V, 30 pA; b 1.9 V, 10 pA; c -0.75 V, 30 pA; d -0.25 V, 10 pA; e, f -1.5 V, 15 pA.
