Computer simulation of heating of nickel films on two-layer graphene

The behavior of a nickel film on two-layer graphene in the temperature range 300 K $\le T\le$ 3300 K has been investigated using the molecular dynamics method. The kinetic, structural, and mechanical properties of this film have been compared with the corresponding characteristics of a similar nickel film on single-layer graphene. It has been shown that the second layer of heated graphene plays a stabilizing role in retaining the hexagonal cellular structure of the graphene layer contacting with the metal.
