Fig. shows that the number of adsorbed molecules at the end of the simulation is equal to the number of molecules initially placed on the surface up to a certain value of the initial coverage. Beyond this critical value, a plateau is reached and the final coverage does not increase further regardless of the initial coverage. This maximum number of adsorbed molecules is 170 for SA, 121 for GMO and 120 for GMS. Consequently, the area per molecule at maximum coverage is 17.96 Å2 for SA, 25.23 Å2 for GMO and 25.44 Å2 for GMS.
