Abstract

The nonmonotonic dependence of the superconducting transition temperature on the number of CuO₂ layers (n) per unit cell for mercury-based cuprate systems is investigated with the framework of the electrostatic model and the Ginsburg-Landau theory. It is found that the largest value of the normalized density of states is 1.8 when n = 3, which corresponds to the highest T_c in this series. Using reasonable parameters we predict an upper limit of T_c of 160 K.
