“…It can be seen a significant difference in melting points between free-standing graphene which was studied in reference [48] (around 8000K) and graphene layer in hybrid models in this study (around 4550K -graphene/h-BN and 5150K -graphene/h-BN/graphene). To clarify this difference, some points related to free-standing graphene as well as hybrid materials are presented here.…”

“…Next, a temperature T i (T i = 8000K) is chosen. This chosen temperature is higher than the melting point of free standing graphene [48] or h-BN [49] to observe the evolution of the models upon heating. The system is heated from the temperature T 0 to T i in the canonical ensemble.…”

“…Therefore, the approach proposed in the present paper can be considered as a theoretical alternative to the model based on the ideas about the main role of intrinsic defects in crystal melting; 4. The most important role of the "soft" bending mode in the mechanism of graphene melting is evidenced by the fact that while ignoring the bending degree of freedom, MD simulations [20] lead to a much overestimated (almost twice compared with the generally accepted value ≈ 4500 K [6,8]) melting temperature of graphene. On the contrary, taking into account the bending mode, we can construct a self-consistent theory of 2D melting and obtain a realistic estimate of the melting temperature, as well as find the value of a parameter similar to the well-known 3D Lindemann parameter.…”

“…Có thể thấy rằng, ở nhiệt độ 3810 K, tỷ lệ các vòng có kích thước lớn giảm, điều này liên quan đến việc đứt gãy của các vòng khi nhiệt độ tăng. Hiện tượng này cũng đã được chỉ ra trong nghiên cứu đối với mô hình graphen hai chiều [41].…”
