About

John Fisher is an Associate Professor at Chonnam National University in South Korea. His research focuses on the development and characterization of advanced materials, particularly in energy storage and piezoelectric ceramics. Recent articles include studies on the fabrication of textured electrostrictive ceramics and the growth of single crystal materials such as (Na0.5Bi0.5)TiO3 and (K1−xNax)NbO3. He continues to explore microstructural evolution and grain growth in polycrystalline materials to enhance their properties.
