The electron-phonon interaction in Li-doped carbon clathrates hex-LiC40 and hex-Li2C40 has been investigated from first principles. Although the characteristic phonon frequency and electron-phonon interaction are large, the electronic density of states is relatively low which finally gives an electron-phonon coupling constant lambda=0.46 for Li2C40. Hole-doping is expected to provide higher T-c than n-doping in hex-C-40.

Abstract

The electron-phonon interaction in Li-doped carbon clathrates hex-LiC40 and hex-Li2C40 has been investigated from first principles. Although the characteristic phonon frequency and electron-phonon interaction are large, the electronic density of states is relatively low which finally gives an electron-phonon coupling constant lambda=0.46 for Li2C40. Hole-doping is expected to provide higher T-c than n-doping in hex-C-40.
