Indirect interaction in Ag and Pd adsorbed layers on the Mo(1Â 1Â 2) surface

▸ The structure of Ag/Mo(1 1 2) has been studied by LEED. ▸ DFT calculations show that adjacent Ag or Pd adatoms attract each other. ▸ The missing-row p(1 × 2) Pd structure is formed due to indirect interaction. ▸ The corresponding period of Friedel oscillations is originated by surface sheets of Fermi surface of Mo(1 1 2).
