Abstract

The sheet-charge model is applied to study charge distribution and intrinsic T_c among the CuO₂ planes in HgBa₂Ca₂Cu₃O_{8 + δ}. This model enables us to achieve nonhomogeneous dependence of T_c on both hole concentration and pressure. Calculations show that there exist two different parabolas of T_c(P) for the type-I and type-II CuO₂ planes, which have a kink at high pressure. Based on the recent experiment of Jover et al., we suggest that at low pressure the T_c is the intrinsic T_c of the type-I CuO₂ planes, and at the highest pressures the effect of the type-II CuO₂ planes dominates.
