| Research Abstract |
We searched for novel superconductors in compounds with three-dimensional conductive covalent networks. Although no supercondutivity was observed so far, KB6 is one of such compounds, and heavy hole-doping was suggested to be a possible way for superconductivity. We discovered a novel paramagnetic compound Ca3Co4Ge4, with three-dimensional network of Co-Ge covalent bonds. From broad investigation of electronic structures, we designed hypothetical compounds MgFeGe and LiCoGe to reproduce electronic structures of Fe pnictide superconductors.
