From: Relation between the strength and dimensionality of defect-free carbon crystals
Dependence of the strength of interatomic bonds of carbon crystals on the its dimensionality: blue squares are the strength values obtained by the results of ab initio calculations and red circles are the results of calculation by the modified Brenner potential for angles between interatomic bonds in the unstrained state and at the critical strain of crystal instability, respectively
