Figure 3

(a) Lattice vibration dispersion and (b) phonon density of states of CP1 borophene along the Brillouin zone (BZ). (c) The difference of the real part of the electronic Eliashberg function $\Re [g^2{F}_{n\mathbf{k}}^c\left(\omega \right)-g^2{F}_{n\mathbf{k}}^v\left(\omega \right)]$ (shown by the solid curve), between the (c) top valance state at $▴$ and the bottom conduction state at $•$ and; (d) the bottom conduction state at $▴$. See Fig. 2 for the symbols. The shaded regions are the Eliashberg function of the valence (red) and conduction (green) states. (e) Excitonic Eliashberg function showing the strength of the exciton-phonon couplings of the lowest bright exciton at different temperatures.
