The dynamic stabilities were confirmed by the positive phonon magnitudes. The corresponding phonon band structures were obtained from a high resolution of the tetragonal and hexagonal Brillouin zones according to Togo et al. . The electronic band structures were obtained using the all-electron DFT-based ASW method and the GGA XC functional . The VESTA (Visualization for Electronic and Structural Analysis) program was used to visualize the crystal structures and charge densities.
