Dear Yuehua,

    Leave along whether it is difficult, is electron-phonon coupling physical
meanful for nonmetal?  My anwers could be wrong, but what I leant is that two
electrons coupled by lattice vibrations to form a pair, which can only happen
in metals (usually weak metals).  Please correct me if I convey wrong
