The chemical stability is confirmed by calculating the cohesive energy (-5.68 eV/atom) using Eqn. 1. This large negative value of cohesive energy suggests that p-BCN is a stable monolayer. Additionally, the calculated formation energy (Eqn. 2) ( ) is -2.07 eV/atom thereby confirming the feasibility of it's experimental synthesis. The dynamical stability is calculated by phonon band dispersion (Fig. ).
