Description

Transition temperature Tc of La2-xSrxCuO4 is investigated theoretically within the frame work of BCS phonon mediated pairing mechanism, based on the electronic structure derived by Kamimura and Eto. Effective electron phonon coupling constant λ is estimated by fitting the calculated T-linear resistivity to the epxerimental data. Then Tc is calculated as a function of x with use of the density of state for the Cu dz2 upper Hubbard band. The calculated x-dependence of Tc agrees well with experimental data. (orig.)
