Theoretical modelling of the adsorption of thallium and element 113 atoms on gold using two-component density functional methods with effective core potentials

► In this study we model the adsorption of the superheavy element 113 on gold surfaces. ► The binding energy of element 113 and thallium is calculated for cluster models. ► For many different binding sites, element 113 binds weaker by 90 ± 15 kJ/mol.
