Communication: Critical behavior in graphene: Spinodal instability at room temperature

Abstract:
At a critical spinodal in-plane stress τC, a planar crystalline graphene layer becomes mechanically unstable. We present a model of the critical behavior of the membrane area near τC 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, τC, the in-plane strain behaves as τC-τ1/2 for τ < τC.

Critical Region, Critical Values and Significance Level
In hypothesis testing, a sample statistic is converted to a test statistic using z, t, or chi-square distribution. A critical region is an area under the curve in probability distributions demarcated by the critical value. When the test statistic falls in this region, it suggests that the null hypothesis must be rejected. As this region contains all those values of the...
