| dc.description | The lattice gas model sets up a regular array of points on a plane for particles in the gas phase to adsorb on. In reality, more than one energy levels on a solid surface are available for the ad-particles. Taking the lateral interactions into consideration, things are more complicated: the most probable energy level for an ad-particle to stay may depend on whether there are particles already adsorbed. At certain coverages, the ad-particles may move away from regular surface cell. A two binding states lattice gas model is introduced to simulate the real surface phenomena using transfer matrix method. | en_US |
| dc.description | Frequently examined thermodynamic quantities like coverage, isosteric heat and internal energy are related to the grand canonical partition function of specific systems calculated from the transfer matrix; the desorption rate is expressed in terms of the adsorbate chemical potential under quasi-equilibrium conditions. Using a conventional lattice gas model, we reexamined certain equilibrium properties of 2-d gases on a square lattice, specially we calculated the entropy per site to analyse the possible structures formed on surfaces. We gave the kinetics and dynamics on triangular lattice a systematic study, including multi-interactions. Also examined are equilibrium properties of gases on a honeycomb lattice. | en_US |
| dc.description | Using the two binding states lattice gas model, we fitted the isotherm and desorption trace of CO on a Rhodium (110) surface to a recent experimental result almost perfectly. | en_US |
