Figure 13. Tensile deformation induced fracture in monolayer hBN. (A) and (B) Comparisons of the stress-strain curve upon static tensile loading along the armchair and zigzag direction, respectively; (C) and (D) Size effects on mechanical response along the armchair and zigzag direction, respectively. DFT: Density functional theory; hBN: hexagonal boron nitride; ML: machine learning.
