Abstract

The theoretical description of the adsorption of atoms on surfaces is still a big problem especially when the atoms involved are very heavy such that relativistic effects play an important role. During the last years we have developed a relativistic molecular program [1] which solves the relativistic Kohn-Sham equations with the use of various density functionals. We discuss here the adsorption of heavy elements on a Au(100) surface. The surface is simulated by different clusters in order to check at which position the ad-atom is adsorbed. Our main task here is to calculate the difference in the adsorption energies between the super-heavy element 112 and its homologue Hg.
