a Stress-strain relations of Gr monolayer (Gr), BN monolayer (BN), and Gr/BN bilayers under uniaxial tensile loading along the x-axis. Inset depicts the stress-strain relations of Gr, BN, and Gr/BN under uniaxial tensile strains from 0 to 0.018. b The 3D atomic structures of Gr/BN bilayers under 0, 0.01, and 0.018 strain. Atoms are colored according to their height displacements as shown in the color bar below. c, d The first derivative of stress-strain curves \((d \sigma / d \varepsilon )\) and max height displacement of Gr/BN bilayers under uniaxial loading along the x-axis, respectively.
