Linear Electron-Hole-Electron Pair Model of High-Temperature Superconductivity in La(2-x)M(x)CuO4 and YBa2Cu3O(7-y): 2, Dependence of the Superconducting Transition Temperatures on Pressure and on Hole Concentration

摘要

On the basis of the linear electron-hole-electron (e-h-e) pair model, we discuss how the number of holes (i.e., formal Cu(sup 3+) sites), and an applied pressure, affect the superconducting transition temperatures (Tc) of La(sub 2-x)M(sub x)CuO(sub 4) and LBa(sub 2)Cu(sub 3)O(sub 7-y)(L = Y, Sm, Eu, Gd, Dy, Ho, Yb). We also examine the origin of the plateaus in the (Tc) vs oxygen content pilot of YBa(sub 2)Cu(sub 3)O(sub 7-y) within the framework of the linear e-h-e pair model. 17 refs.
