Experimental absolute step and kink formation energies on Pb(111) vicinal surfaces
Experimental absolute step and kink formation energies on Pb(111) vicinal surfaces
Three-dimensional crystallites of Pb, equilibrated at various temperatures and imaged by scanning tunneling microscopy at temperature, have provided the basis for a quantitative determination of absolute step free energies and kink formation energies of vicinal Pb(l 11) surfaces. The anisotropy of l...

Three-dimensional crystallites of Pb, equilibrated at various temperatures and imaged by scanning tunneling microscopy at temperature, have provided the basis for a quantitative determination of absolute step free energies and kink formation energies of vicinal Pb(l 11) surfaces. The anisotropy of large (111) facets was evaluated as a function of temperature. Products of radius times local curvature for A and B-steps of these facets were calculated and their dependence on temperature fitted by theoretical expressions. Absolute values of step energies at 0 K are f(1A) (0) = 131 meV and f(1B)(0) = 117 meV, with the corresponding kink energies Of epsilon(kA) = 40.0 meV and epsilon(kB) = 60.3 meV.
