| Outline of Final Research Achievements |
In this research, we focused on materials having covalent network with light elements. We discovered new superconductors SrPt2Sb2 (Tc=2.1K), Ln2SnC (Tc=5.2K), YRe4Si2 (Tc=3.2K), LuRe4Si2 (Tc=3K), Ba(Cu,Si)2 (Tc=3K) by searching for new superconductor having covalent network, tetrahedron, octahedron and honey comb lattice. And, we cleared main role in these superconductors in terms of electronic state and structural feature. In the research of superconductivity in carrier-doped AlN, the lattice constants of superconducting samples are longer than that of commercial AlN. We cleared that carrier in superconducting AlN samples is doped by extra Al or N.
