The stability of the 2D fullerene sheet exhibits a consistent decline with an increasing concentration of B-N dopants. Structurally, a more negative cohesive energy material is generally considered more stable. Notably, pristine C 60 demonstrates a significantly higher negative cohesive energy, highlighting its superior structural stability compared to its doped counterparts, which exhibit distinct variations in other physical and electronic properties. To comprehensively assess the stability of these nanosheets, lattice dynamical analysis via phonon dispersion calculations is typically recommended. However, due to the large unit cell size and computational limitations, such an evaluation is beyond the scope of the present study. Nevertheless, prior research confirms that C 60 polymers exhibit positive phonon frequencies throughout the Brillouin zone, signifying their dynamical stability and additional ab initio molecular dynamics performed for the doped sheets .
