Graduate School
Undergraduate School

Academic Degree
Ph. D (Engineering)
Field of Specialization
Solid State Chemistry, Physical Chemistry, Ceramic Materials
Outline Activities
Prof. Hayashi’s group covers the field of Applied Inorganic Chemistry, including synthesis of novel functional ceramic materials, and fundamental researches based on solid state chemistry and physics. They are studying not only typical metal oxide-based ceramics but also novel mixed-anion compounds with nitride, hydride, and electride. Their recent interest includes two-dimensional nanosize compounds prepared from metal carbides. Materials functions such as ionic conduction/exchange and dielectric/conductive properties are applied to development of energy storage and electronic devices.
