INDIRECT INTERACTION BETWEEN ADATOMS ON Ni(100) SURFACE

  • 1. 河南师范大学物理系

Abstract: The indirect interaction between adatoms are studied by using tight-binding model and one-electron theory. We found that the introduction of impurity atom Cu makes the peak value of the interaction energies to increase, and the introduction of Co makes that value tp decrease. Using the relation between the indirect interaction energies and the relative positions of the adatoms, we explain the structure of H or O monolayer chemisorbed on Ni(l00). In addition, it is found that the interaction energies have a damped oscillation behaviour with the decrease of the coupling strength between the adatoms and the host atoms.
