Outline of Final Research Achievements

Solids exhibiting a complicated band structure (i.e., their peculiar electronic nature) host various interesting physical phenomena, such as topological phases of matter, superconductivity, thermoelectric properties, or complicated spin structures. To identify, understand, and eventually exploit such features are key targets of research in solid state physics. Here the focus was lying on topological features combined with superconductivity. The approach was to dope into promising starting materials, such as SnTe, GeTe, Cd3As2, and others. Superconductivity in SnTe and GeTe (in the latter it was discovered for the first time) and its relationship to valence instabilities was explored. Such valence instabilities are discussed as a possible origin of enhanced superconducting interactions. Cd3As2, famous for its unconventional so-called "topological" nature, was also explored. By doping, a fine control was achieved over its interesting features.

Academic Significance and Societal Importance of the Research Achievements

本研究では、超伝導と相互作用するトポロジカル電子相を検出することを目的とした。電子物性におけるトポロジーは、約15年前に始まった固体物理学の比較的新しい概念であり、関連した物性は当初、低温/強磁場のような特殊な環境でのみ発現すると考えられていた。本研究によって、多くの物質が様々な環境において、超伝導を含むトポロジカルな物性を発現しうることが明らかとなり、将来的な量子計算機等への応用につながる知見が得られたと考えられる。
