Abstract
In this paper we present a low-energy ion scattering (LEIS) study of the mobility of Ag and Fe adatoms on the Ag(100) surface. We determined the onset temperature for Ag adatom diffusion on Ag(100) to be 160(5) K. From this value we estimated the activation energy barrier for self-diffusion on Ag(100) to be 0.40(5) eV. Single Fe adatoms on the Ag(100) surface were found to exchange site with Ag atoms from the first layer, starting at a temperature of 130(10) K.
