| Research Abstract |
I have succeeded to grow the rectangular hollow tube oxide crystals with rutile-type structure in a supercritical oxygen fluid under ultra-high pressure and temperature (a few GPa and thousand Kelvin). Our obtained crystals show very unique crystallographic morphology in comparison with previous study. Our research provides useful and important information on glass formation ability, crystal growth mechanism and knowledge for a development of novel functional materials under high pressure.
