Abstract:
A two-dimensional model of a multilayer material and a procedure for simulating its properties based on global optimization methods are proposed. This model is applied for the case of a two-dimensional crystal. Global minima of the interaction energy of the material's atoms are found, and geometric characteristics of its corresponding equilibrium states are described. The resulting lattices, in particular graphene's lattices, agree with experimental data, which confirms the validity of the proposed approach. This approach can be extended to a wider class of layered structures, and it can be used for determining the mechanical properties of materials.
Key words:
two-dimensional crystals, optimization methods, graphene-like structures, equilibrium state.
