Outline of Final Research Achievements

In this study, we have investigated the origin of superconductivity on the pressure induced superconductors and looked for the new novel physical properties under pressure. The pressure phase diagram of pressure induced superconducting materials were submitted and suggested the origin of its superconductivity. In addition, we found out a few kinds new pressure induced superconducting materials.
