Outline of Final Research Achievements |
In this research project, we demonstrated the chemical vapor deposition of self-organized columnar structures, mainly in hafnium oxide (HfO2) and lutetium oxide (Lu2O3)-based materials. First, we selected Sr organometallic compound precursor to prepare SrHfO3 films. In the HfO2-MgO and HfO2-TiO2 systems, we found the formation of stoichiometric double oxides, and in the HfO2-Lu2O3 system, it was found that the crystalline phase changed continuously depending on the Hf/Lu molar ratio. We also found that self-organization occurred in the Lu2O3-MgO and Lu2O3-Al2O3 systems.
