Abstract
The time evolution of adatom and vacancy islands on an Ag(110) surface is s tudied by using a variable-temperature ultrahigh vacuum scanning tunneling microscope. The islands are created by Ar+ ion sputtering at low temperatur es and at very low fluxes (similar to 0.004 ML s(-1)). The area of both kin ds of island decreases linearly as a function of time, at least for small i slands. The experimental results are compared with kinetic Monte Carlo simu lations.
