【Abstract】 A combination mechanism of phonon-exciton is proposed according to the character of highT_c superconductors and the calculated resultes of energy bands and a T_c formula is deduced within the strong coupling Eliashberg theory. This theory can be used to explain the properties of isotope effect and coherent length in high-T_c superconductors.更多还原
