| Outline of Final Research Achievements |
In this research, we focused on the systematization of flux crystal growth technology. In particular, we considered the following four approaches.
(1) Proposal of a novel crystal growth process by use of a flux screening (FS) to obtain multipoint data, (2) Growth of oxide crystals by FS method using super fluxes, (3) Growth of non-oxide crystals by FS method, and (4) Footholds to create a flux crystal map
Through this research period, we have obtained various flux crystal growth conditions, that is recipes, to systematize the flux crystal growth technology. By effectively utilizing these recipes, we have found a path to data science, and realized a new process of creating phase diagrams containing supersaturated state.
