| Research Abstract |
We proposed a new guiding principle to improve thermoelectric performance and confirmed the efficiency in Al-based quasicrystals. We discovered self-compensation phenomena for doped-electron in β-rhombohedral and α-tetragonal boron. On the other hand, the self-compensation phenomena did not occur in α-rhombohedral boron and we found superconductive transition by Li-doping.
