Achieving two-dimensionally (2D) ordered surface wrinkle patterns is still challenging not only for the atomic-thick 2D materials but also in general all soft surfaces. Normally disordered on isotropic surfaces can be rendered via biaxial straining. Here, we report that 1D and produced by sequential wrinkling controlled thermal straining vertical spatial confinement. The various hierarchical generated our method are highly periodic, hexagonal crystal symmetry obeyed. More interestingly, these maintained suspended monolayers after delamination from underlying which shows great application potentials. Our new approach simplify patterning processes layered reduce risk of damage compared to conventional lithography methods, numerous engineering applications require nanoscale texturing could empowered.
