The bond length between each atoms increases (decreases) with increasing tensile (compressive) biaxial strain (Fig. ). However, the rate of variation is less in the B-N bonds as compared to other bonds. This result is attributed to the shorter bond length with stronger inter-atomic interaction and quasi-sp 3 hybridized covalent bonding between the B and N atoms. The C1-N bond also varies slowly showing it's rigidity toward the strain. Similarly, the bond angle between C1-N-C2, B-N-C1, B-N-C2, also increases monotonically with the increase in strain (Fig. ). However, the bond angle between B-C1-N, N-C1-N decreases in the same fashion. This reduction is due to the geometrical positioning and re-arrangement of atoms by strain. Similarly, the thickness (ℎ) decreases monotonically with the applied tensile strain. It suggests that the material tends to extend horizontally and compress vertically. This is analogous to stretching the dough and it's relative deformation. Thus, it is clear from the analysis that a geometrical deformation is created due to the applied strain.
