“…To simulate the evolution of the system addressed in the computational results section and in the Supporting Information of this paper, we used the two-dimensional kinetic Monte Carlo (kMC) model similar to that described previously. ,− The hop rate of Au–SR complex from site i to site j on Au(001) was calculated using the Arrhenius equation: where T is the temperature of the substrate, ν 0 is the attempt frequency, and k B is the Boltzmann constant. We set ν 0 to 10 12 Hz.…”

We have studied decanethiolate self-assembled monolayers on the Au(001) surface. Planar and striped phases, as well as disordered regions, have formed after exposing the Au surface to a decanethiol solution. The planar phases that we observe have a hexagonal symmetry and have not been previously reported for thiols on the Au(001) surface and have lower coverage compared to that of the other known thiol planar phases such as the square α phase. The striped phases that we observe are similar to the previously reported β phase but still feature unit cells that cannot be modeled as the archetype, and the coverage is also somewhat lower. The disordered decanethiolate regions are more dynamic compared to the ordered phases, confirmed with I ( t ) spectroscopy. This suggests that in these regions the coverage is too low in order to form ordered decanethiolate phases. Our findings contribute to the growing family of possible decanethiol formations on the Au(001) surface, for which still less is known compared to the extensive overview present for the Au(111) surface.

“…The recent advances in the production of one-dimensional islands on vicinal surfaces with a narrow terrace-size distribution [1][2][3][4] and low-index semiconductor surfaces [5][6][7][8] have motivated the study of models that describe the growth of one-dimensional islands on surfaces under certain conditions [2,[9][10][11][12]. Therefore, one of the central problems is to determine the factors that affect the length of one-dimensional structures.…”

“…The second one is based on the rate equations [17]. And the third one is based on kinetic Monte Carlo simulations [11,12,[18][19][20][21]. However, the most popular approach is to use a combination of rate equations with kinetic Monte Carlo simulations and then to compare their results [13,14,[22][23][24][25][26][27].…”

“…Attempts to use distribution to calculate binding energy have been made in experimental works [3,4]. However, the discrepancy between the experiment [4] and the theory [12] turned out to be significant. Moreover, the theoretical models did not take into account the fact that during annealing or cooling the transition from one state of thermodynamical equilibrium to another occurs through a non-equilibrium state [11].…”

In this paper, a novel analytical expression for the size distribution of one-dimensional structures at thermodynamic non-equilibrium is derived. The expression is obtained using one-dimensional lattice gas model. Ostwald ripening and decay of short one-dimensional islands is taken into account. The theoretical results are compared with kinetic Monte Carlo simulations and the experimental size distribution of one-dimensional wires. A correct method of extracting the binding energy from the experimental size distribution in one dimension is proposed.
