Abstract

A microscopic model of adsorption in cluster forming systems with competing interaction is considered. The adsorption process is described by the master equation and modelled by a kinetic Monte Carlo method. The evolution of the particle concentration and interaction energy during the adsorption of particles on a plane triangular lattice is investigated. The simulation results show a diverse behavior of the system time evolution depending on the temperature and chemical potential and finally on the formation of clusters in the system. The characteristic relaxation times of adsorption vary in several orders of magnitude depending on the thermodynamic parameters of the final equilibrium state of the adsorbate. A very fast adsorption of particles is observed for highly ordered adsorbate equilibrium states.

团簇形成系统的吸附时间标度

摘要

考虑了具有竞争性相互作用的团簇形成系统中吸附的微观模型。吸附过程由主方程式描述，并通过动力学蒙特卡洛方法进行建模。研究了颗粒在平面三角形晶格上吸附过程中颗粒浓度和相互作用能的变化。仿真结果表明，系统时间演化的不同行为取决于温度和化学势，最后取决于系统中簇的形成。吸附的特征弛豫时间根据被吸附物最终平衡状态的热力学参数，在几个数量级上变化。对于高度有序的吸附物平衡态，观察到非常快速的颗粒吸附。
