| Research Abstract |
The aim of this study is to obtain high quality functionalized materials by realizing appropriate doping technology under the variety of synthesis process, including high pressure and high temperature process, solid-state reaction, and thin film growth technique. By cooperating with the researchers in theoretical and ultimate structural analysis field, we tried to control the effective doping technology for the functionalized nitride and oxide ceramic materials. Successful doping with large misfit in highly covalent rigid crystals was achieved. Theoretical and structural analyses clearly show the occupancy site in the crystal by defect complex model. This fact suggests the way of functionalization by doping in the large lattice misfit systems. New multifunctional oxide polycrystalline materials have been developed through the atomic modification which controls high temperature matter transport in grain boundary and interface. Synthesis and characterization of oxide semiconductor films were performed aiming to develop electronic devices by utilizing the advantages in the concept of Nano-Dopant.
