1 Supplementary Information for A Three-Dimensional Phase Diagram of Growth-Induced Surface Instabilities

Supplementary figures Supplementary Figure S1 | The transition process from creases to folds. (A) Comparison between the calculated phase diagram and experimental results for the transition from creases to folds. (B) Sequences of experimental images to show the transition process from creases to folds with increasing mismatch strain. 3 Supplementary Figure S2 | Calculation of the phase boundary between the flat and wrinkled states. Schematics of (A) a neo-Hookean block and (B) a neo-Hookean film-substrate structure. (C) Calculated critical mismatch strain and (D) critical wavelength between flat and wrinkled states as a function of modulus ratio sf
