Surface Adsorption Energy Calculation
The necessary tools to perform the surface adsorption energy is shown in this page.
Note: The page is under a continuous developing stage.
One adatom is placed on top of the created surface at the next atomic layer distance. There could be different positions of the adatom on top of the surface, such as bridge-site, four-fold site, etc. The entire structure is then relaxed to determine the adsorption energy. It may be found that depending on the adatom site, the adsorption energy will be different for various adsorped sites. The height of the relaxed adatom is also measured from the top surface layer.
