Атомістика впливу силового поля на довговічність карбін- графенових наноелементів та аналогічних двовимірних наноструктур.

Atomic mechanisms of the fluctuation-induced breaking of contact bonds in carbyne–graphene nanoelements under the force-field conditions are considered. Existence of two components of the force-field effect on the durability of carbyne–graphene nanoelements and similar two-dimensional nanostructures is ascertained, namely, (i) a decrease in the energy-barrier height under the force action and (ii) a decrease in expenditure of energy for breaking the bond due to the release of elastic-deformations’ energy accumulated within the nanoelement. As shown using the example of a carbyne– graphene nanoelement, the impact of the force field can cause a drop in durability by tens of orders of magnitude. This is a manifestation of the synergy of the temperature and force-field effects on the stability and durability of nanostructures. Approximate analytical dependences are derived, which enable predicting the durability of such two-dimensional nanostructures, in particular, as straintronics elements, with sufficient accuracy. From a theoretical point of view, the proposed approach may be considered as a generalization of the Arrhenius theory of reactions to the case of forcefield action. [ABSTRACT FROM AUTHOR]
