Figure 5

AFM image 5 × 5 μm2 of the evolved morphology of a 3nm-thick film deposited at R = 0.04 nm/min (a) and the relative height distribution (b). In red we draw the sum of the Gaussian fits (thin lines) of the peaks related to the uncovered substrate and the molecular layers. In (c) we propose a sketch of the molecular assembly at the end of the spreading process for the 3 nm-thick film. This sketch is a suggestion just for representation. The white line is a marker of size 1 μm.
