P.‐Y. Chen, R. H. Hurt, I. Y. Wong and co‐workers demonstrate a hierarchical graphene surface architecture generated by using various sequences and combinations of extreme mechanical deformation, as shown in the false‐colored SEM image. As described on page 3564, the sequential patterning approach enables the design of feature sizes and orientations across multiple length scales which are retained during mechanical deformations of similar extent. This results in sequence‐dependent surface topographies with structural memory.
