Extended Data Fig. 7: Atomic site-resolved surface strain of Pt[n(111)-(100)] surfaces.
From: Site-specific reactivity of stepped Pt surfaces driven by stress release
(a) Pt(322) surface and (b) Pt(544) surface with a terrace width of 1.1 nm (n = 5) and 2.1 nm (n = 9), respectively. The terrace width is indicated by double arrow lines. Surface sites correspond to atoms in the top layer of the side views (upper panels). 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.
