| Surface diffusion of palladium, Θ=2 ML, on a tantalum microcrystal was studied by means of field electron emission microscopy within the temperature range 665--790 K. The observed sharp moving boundary-diffusion proceeds with an activation energy ranging from 1.25 to 1.7 eV/atom, depending on the crystallographic direction. |
