By using numerical simulation we have studied the diffusion of isolated lead atoms on Cu(110). The calculations rely on a phenomenological many-body potential derived in the framework of the second-moment approximation of the tight-binding method, with parameters fitted on the physical properties of the bulk crystals of copper and lead and to the copper–lead phase diagram. Static calculations, at...
We have studied the surface diffusion of Pb on Cu(110) at low coverage by Rutherford backscattering spectrometry (RBS) in the 500-800K temperature range. The spread, after annealing, of a deposit achieved at room temperature is measured along the [110] and [001] directions, providing the corresponding diffusion coefficients. The activation energy is found to be close to 0.6eV along both directions:...
