Phonon and EPC study on MgC2 at ambient pressure. (a) Phonon dispersion curve and total phonon DOS of MgGNR at ambient pressure. The size of each blue circle is proportional to the magnitude of λqν. (b) Eliashberg function and λ(ω). Lattice displacements by two phonon modes, (c) q1 and (d) q2, provide the large contribution to λ. Blue arrows represent the displacements. The frequencies of q1 and q2 are 45.8 meV and 142.9 meV, respectively.
