    • Incorporating misfit dislocations at the interface between film and substrate is a common mechanism to relieve elastic strain due to the lattice mismatch between film and substrate. In the system studied here, this mismatch is considerable: The nearest neighbor distance of bulk Ag is 7% larger than that of Ru.

    • The relaxation time is related to the mobility of the holes, which depends on the atomic diffusion mechanisms for their motion [see, for example, (16)].

    • The misfit dislocations run parallel to the surface, with their core located between the first and second atomic layers (27, 28)-in this system, between the Ag monolayer and the Ru substrate. Their Burgers vectors are perpendicular to the dislocation lines and point from the hep-stacking site to the fee-stacking site, or vice versa, rendering them partial dislocations of pure edge character.
