Extended Data Fig. 2: Atomic site-resolved surface strain of Pt(221) surface with a terrace width of 0.8 nm (n = 3).
From: Site-specific reactivity of stepped Pt surfaces driven by stress release
Surface sites correspond to atoms in the top layer of the side view (upper panel). τ is intrinsic tensile surface stress, which is spontaneously released by introducing step to break symmetry, accompanied by the simultaneous generation of compressive surface strain. The terrace width is indicated by double arrow lines.
