4 Changes in Surface Stress Associated with Underpotential …
Fig. 4.16 a The changes in surface stress g due to alloying and b the surface stress g of surface
alloy, plotted versus the calculated difference in atomic radius r between adsorbate and substrate
atoms for the surface alloys in which the radius of adsorbate atom is larger than that of the substrate
atom [75]. The unit of the abscissa in Fig. 4.16a and b is expressed by Ångström (Å = 0.1 nm).
