Oxides for high temperature superconductivity and beyond

摘要

In this paper, I shall briefly summarize the present state of high temperature superconductivity research and development together with an assessment of the prospect of yet a higher transition temperature and an outline of challenges facing today's of practitioners of high temperature super-conductivity science and technology. The extensive knowledge acquired in the last decade in high temperature superconducting science and materials may usher in a new era of material engineering, which I would like to call mesomaterial engineering for the fabrication of perovskite and related oxide superlattices, a new class of materials for science and technology. Therefore, I shall also present the rationale behind this effort and the promises of the new materials, together with a list of several preliminary successful examples.
