New measurement technique quantitatively determines the effect of wrinkles on the stiffness of graphene

A new interferometry technique was used to determine that the softening of graphene grown by chemical vapor deposition (CVD) is dominated by static wrinkles rather than flexural phonons. “The effect of intrinsic crumpling on the mechanics of free-standing graphene.” (highlight slide) Nicholl et al., Nat.
