Schematic representation of step‐down, step‐down (dimer) and upper‐step self‐diffusion processes on Mg(0001): a) step‐down [11$\bar{2}$ 0]‐step; b) step‐down [$\bar{1}$ $\bar{1}$ 20]‐step; c) step‐down (dimer) [11$\bar{2}$ 0]‐step; d) step‐down (dimer) [$\bar{1}$ $\bar{1}$ 20]‐step; e) upper‐step [11$\bar{2}$ 0]‐step; f) upper‐step (dimer) [$\bar{1}$ $\bar{1}$ 20]‐step. Green‐colored atoms mark the initial, while red‐colored atoms mark the final positions.
