Since the structural clarification for the fundamental component is provided, the conformational stability of the material is figured out through formation energy. The equation necessary to compute the formation energy is given underneath [42, 43].
\begin{equation} E_{\text{Form}}=(1/s)[E\left(Kagome-PNT\right)-sE\left(P\right)]\nonumber \\ \end{equation}
The factors handled in the calculating formation equation (EForm) are the energy of the fundamental component –E(Kagome-PNT), procurable number of phosphorus (P) atoms in the fundamental component – ‘s ’ and energy of a single P atom –E(P). By wielding the aforementioned parameters, the formation energy is assessed to be -3.883 eV per atom. The non-positive measure ofEForm verifies the conformational stability of the fundamental component. This is ascribed to the complex conformation of Kagome-PNT that follows the local co-ordination of α-P and global symmetry of β-P form [44]. In addition, to verify the dynamical stability of chief component Kagome-PNT, phonon-bands-spectrum is plotted as shown in Fig. 2. It is revealed that there is no imaginary-frequency noticed in the phonon spectrum, confirming the dynamical-stability of Kagome-PNT.
