Structure-Property Relationships of Chemically CharacterizedThallium Cuprate Superconductors

本项目旨在系统地研究铜酸铊中铊含量和载流子浓度对超导性能的影响。对于许多铜酸铊体系，超导性能将与结构和化学组成（包括空穴浓度和氧含量）相关。所提出的研究将有助于了解超导机制，也将有助于优化合成过程和化学成分，以获得更高Tc的更均匀的材料，或制备新材料。

This project is aimed at a systematic investigation of the variations of superconductive properties with thallium content and carrier concentration in thallium cuprates. Superconductive properties will be correlated with structure and chemical composition, including hole concentration and oxygen content, for a number of thallium cuprate systems. The proposed study will help to gain an understanding of the superconductive mechanism, and will also help to optimize synthetic procedures and chemical compositions required for more homogeneous materials with higher Tc, or for the preparation of new materials.
