关于高Tc问题的一个建议

我们建议:把超导体分成A型和B型两种。前者,λ<Λ,后者,λ>Λ。Λ的物理意义在正文中给出。本文分析表明了,有效声子谱对这两种超导体T_c的影响是不同的,因而提高它们T_c方法也是不一样的。提高A型超导体T_c的最有效方法是增大λ。提高B型超导体T_c的最有效方法是增大又λ〈ω²〉。 关键词：

A SUGGESTION ON THE HIGH Tc PROBLEM

We suggest that the superconductors should be divided into two types, type A and type B, for the former, λ<Λ and for the later, λ>Λ. The meaning of Λ is given in this paper. Our analysis shows that the influence of effective phonon spectrum on the transition temperature of these two type superconductors are different and the ways for raising their transition temperature are different also. For type A superconductors, the most effective way for raising T_c is to increase λ, whereas for type B superconductors, is to increase λ (ω²).
