In this study, instead of islands, various widths of nanoribbon models were used to analyze the interaction effects between the Cu(111) surface and hBN islands. And the critical size, which represents the size at which the island begins to grow spontaneously, was predicted for islands of various shapes. As a result, it was found that as the chemical potential ratio µ_B/µ_N decreases, Z_B triangular shapes become the most stable, whereas increasing the ratio makes Z_N triangular shapes more stable, and the critical sizes vary accordingly.
