Abstract
The nature of pairing mechanism and T-c of HgBa2CuO4+delta (delta appr oximate to 0.18, T-c approximate to 95 K) have been studied by using f ree electron layered electron gas (FELEG) approach which peoperly inco rporates the unified effects of strong Coulomb correlations, electron - phonon and electron - plasmon interactions. The plasmons provide an additional pairing. Furthermore, Tc mainly arises from plasmon mechani sm.
