Abstract
We present the results of computational and experimental studies of the electronic and structural properties of the Pb/Mo(110) adsorption system. Computational part of this work is based on ab initio density-functional calculations. The obtained results provide detailed geometrical properties of different adsorption configurations and show the influence of lead coverage on the adsorption energy at different adsorption sites. We also consider the formation of ordered lead superstructures on the Mo(110) surface predicted by earlier experimental investigations as well as those indicated by our present scanning tunneling microscopy (STM) measurements. Our STM results show coexistence of two well-ordered surface superstructures in the first lead layer.
