Fig. 3: Phonon and electron-phonon properties of TMC’s.

Phonon dispersions, phonon DOS F(ω) and Eliashberg function α2F(ω) for rock-salt MC (M = Sc-Re). Orange (teal) shading indicates the projection onto carbon (transition metal) modes. The dashed line in the rightmost panel is the cumulative integral λ(ω). Grey panels mark dynamically unstable phases, for which we did not compute the electron-phonon properties.
