报告摘要:The sigma-bonding electrons have large binding energy and are stabilized by strong electron-phonon interaction. If one can lift the sigma-bonding band up to the Fermi level, by chemical doping or other charging effects, the strong binding energy is released, but the residual electron-phonon interaction can still be very strong. This provides a universal scheme for hunting high-Tc superconductors.
