Relation between the strength and dimensionality of defect-free carbon crystals [PDF]
, 2015 On the basis of ab-initio simulations, the value of strength of interatomic bonds in one-, two- and three-dimensional carbon crystals is obtained. It is shown that decreasing in dimensionality of crystal gives rise to nearly linear increase in strength ...
