THE PROXIMITY EFFECT BETWEEN A NONSIMPLE METAL WITH-U CENTERS AND A BCS SUPERCONDUCTOR (I)
具有-U中心的非简单金属与BCS超导体的邻近效应(Ⅰ)

By using McMillan's method, the superconducting proximity effect between a nonsim-ple metal thin film with negative U centers and a thin film of BCS superconductor is analyzed theoretically. It is shown that the superconductivity of this kind of sandwich can be enhanced by this proximity effect. In order to raise Tc, it is desirable to investigate this kind of superconducting materials consisting of S-U multilayers.
