Description
In this work, we continue looking into polarization characteristics of surfaces in the presence of adatoms by means of density functional theory. We follow the changes of these characteristics during possible transitions of an adatom as an event of self-diffusion on the W{110} surface. We analyze the dependencies of these characteristics on the environment of the adatom when it jumps towards and away from small adatom islands. We calculate effective dipole moment and polarizability of W adatom at hollow and bridge sites and compare these with the dipole moments and polarizabilities of the system as a whole.
