On the critical temperature of superconductors
Description
An exact expression for the superconducting transition temperature is derived from the Eliashberg equation at T = T/sub c/ taking the energy gap function in the two-square-well form. The expression is improved for self-consistency by using available tunneling data. It is found to give more restricted values of T/sub c/ than the McMillan equation. The prospects of obtaining high T/sub c/ in alloy systems are discussed within the framework of the new equation. (6 figures, 2 tables) (U.S.)
