Computer simulation of the thermal stability of nickel films on two-layer graphene
Annotation
The structure and the dynamic and mechanical properties of monolayer nickel films deposited on two-layer graphene have been studied in the temperature range 300T3300 K by the molecular dynamics method. A part of the Ni atoms remains on the graphene sheet even at T=3300 K for both one- and two-sided coatings. The radial distribution functions of the upper and lower metal films differ significantly even at T=300 K. The temperature dependence of the horizontal and vertical components of the self-diffusion coefficient of a one-sided nickel film exhibits a jump above 1800 K. No similar specific feature was observed for a two-sided coating of graphene with this film. The stress components acting in the nickel film plane disappear with an increase in temperature for a shorter time in the case of one-sided coating.
