| Outline of Final Research Achievements |
Metallic elements such as Ti and Zr take a hexagonal close-packed (hcp) structure at ambient pressure and temperature and they transform from the hcp structure (α phase) to a hexagonal structure (ω phase) as the pressure increases [1,2]. This ω phase with a hard and brittle nature was successfully used as a strengthening phase in the α matrix. Semiconductors such as Si and Ge and ceramics such as TiO2 and ZnO exhibited phase transformation upon application of high pressures together with intense strains. Because the grain sizes became in the nano range, photoluminescence appeared in Si and Ge due to a quantum confinement effect. The band gaps were changed in TiO2 and ZnO so that their ranges were equivalent to visible light and they were able to split water to generate hydrogen.It was confirmed that functional properties improved in Si and Ge including TiO2 and ZnO.
