Fig. 8.

a, b represent ${\varphi }_s$ versus $En({\zeta }^{\ast })$ plot (with ${\varphi }_s\in (0,0.1])$ and ${\beta }_s$ versus $En({\zeta }^{\ast })$ plot (with ${\beta }_s\in (0,2])$. (c) represent $En({\zeta }^{\ast })$ over $({\varphi }_s,{\beta }_s)$ matrix plot, where $({\varphi }_s,{\beta }_s)\in (0,0.1]\times (0,2]$. The corresponding color bar indicates values of $En({\zeta }^{\ast })$. The values of the other parameters are taken as same, shown in Table 1
