\begin{abstract} |
| 28 |
We present a simple model for the discrepancy in the coverage of a |
| 29 |
Gold (111) surface by two silicon phthalocyanines. The model involves |
| 30 |
Random Sequential Adsorption (RSA) simulations with two different |
| 31 |
landing molecules, one of which is tilted relative to the substrate |
| 32 |
surface and can (under certain conditions) allow neighboring molecules |
| 33 |
to overlap. This results in a jamming limit that is near full |
| 34 |
coverage of the surface. The non-overlapping molecules reproduce the |
| 35 |
half-monolayer jamming limit that is common in continuum RSA models |
| 36 |
with ellipsoidal landers. Additionally, the overlapping molecules |
| 37 |
exhibit orientational correlation and orientational domain formation |
| 38 |
evolving out of a purely random adsorption process. |
