The Reasrch Of Using The Theory Of Intrinsic Superconductive State To Calculate The Superconducting Critical Temperature Of HBCCO Superconductor And Doping

In this thesis, based on the theory of Intrinsic Superconductive State and Analyzing Method of Equivalent Valence Bond for complex structure which are presented by Zou Zhuanghui, the author studies the construction method of equivalent valence bond of some ploytomic superconductors with complex structures, determine a series of general principle for calculation of critical temperature and then determine calculation parameters of some materials, such as:Ne, Va, Ei-E1, neff.In this thesis the calculation parameters of HgBa2Can-1CunO2n+2(n=1,2,3,4,5,6) have been determined and the critical temperatures of six superconductors have been calculated. The results show that:the calculation Tc of six superconductors are consistent with the experiment Tc values of those well.Then, the author explain the reasons of the diffrence between caculated rusults and experimental rusults.On the other hand, we assume that the crystal frames constitute of metal atoms, and then calculate interstitial positions and interstitial radii of HBCCO, and some elements that can enter the doping location have been found out.The author can explain some of the existing experimental rules with the theory of Intrinsic Superconductive State. During the calculations, we find out a rule that the (Ne/Va)3 in HgBa2Can-1CunO2n+2 (n=1,2,3,4,5,6) six kinds of superconductive materials range from about 0.600 to 0.653. In this thesis, the author make a preliminary explanation with this rule,and we have been studying the standard made from (Ne/Va)3.The rule consistent with it in other materials(YBCO,BSCCO,TBCCO),and we are stuyding the correctness that we judge a superconductor from it.Then, the author has explained effects of doping with the theory of Intrinsic Superconductive State.
