| Outline of Final Research Achievements |
Because of their novel quantum states, topological electronic materials are promising components for next generation electronics such as spin devices and quantum computers. We developed both new compounds and novel electronic functionality within a new class of materials called "topological insulators, topological semimetals, and topological superconductors". With regard to materials, phenomena, and functions, several unexpected discoveries were made, which were puplised as 45 articles in high-impact-factor journals, including 5 articles in Nature and sister journals.
