(a) Lower Panel : A linescan taken across the step indicated by dashed black line. Upper Panel: Calculated (DFT) height profile across the step for this linescan. (b) Calculated in-plane (along x-direction) bond-lengths (Δxi+1,I = xi+1 − xi, where i stands for atom index) across the step for this linescan.
