We explain the relationship between the critical temperature 7", and the modulated structure in the Bi-based compounds on the basis of a 2D electron-hole lattice model. The 2D electron-hole lattice is constructed on the Bi-O (and possibly on the Cu-O) planes to neutralize local polarization charges

An origin of superconductivity in YBa 2 Cu 3 O 7Γd is discussed by considering the two dimensional electron and hole systems. In particular, the mechanism to have two peaks where d takes the two value of 1/10 and 1/6 is discussed.
