Figure 4: Binding energy versus strain for various adsorbates.
From: Mechanical work makes important contributions to surface chemistry at steps
(a) Cu(211) and (b) Ni(211) under stress σ[−111] normal to the line of the step: CO atop (black), NH bridge (blue), OH bridge (green) and SH bridge (red). All adsorbates show the same trend with stress: compressive stress increases binding energy. Vertical axes are in units eV.
