Communication: Critical behavior in graphene: Spinodal instability at room temperature
At a critical spinodal in-plane stress τ , a planar crystalline graphene layer becomes mechanically unstable. We present a model of the critical behavior of the membrane area near τ and show that it is in complete agreement with path-integral simulations and with recent experiments based on interfer...

| Summary: | At a critical spinodal in-plane stress τ
, a planar crystalline graphene layer becomes mechanically unstable. We present a model of the critical behavior of the membrane area near τ
and show that it is in complete agreement with path-integral simulations and with recent experiments based on interferometric profilometry and Raman spectroscopy. Close to the critical stress, τ
, the in-plane strain behaves as τ
-τ
for τ < τ
