Energy materials creation chemistry laboratory /Exercise 1

With the aim of achieving results that will contribute to the construction and development of a sustainable society, this research will focus on equipment development and thin film synthesis to synthesize thin films with advanced functionality and further develop energy devices using these thin films. Thin film synthesis targets a wide range of inorganic compounds such as oxides, nitrides, and hydrides. The thin films are obtained by piling up atoms and molecules of raw materials in a high vacuum environment, and their high purity, controlled crystal orientation, and atomic- and nano-scale shape control are utilized to maximize the functionality of each material. Specifically, we plan to synthesize thin films that exhibit the highest hydride ion conductivity at room temperature, lithium ion conductive thin films that can be used in batteries, and aluminum nitride thin films with excellent piezoelectric power generation performance. Furthermore, they plan to develop high-performance energy devices such as all-solid-state batteries using these thin films.

1. Conduct development of thin-film growth equipment and components related to these equipment, and acquire skills and knowledge in equipment development.
2. Master thin film synthesis techniques using deposition methods such as Hals laser thin film deposition, sputtering, and evaporation.
3. Learn a series of methods for evaluating film quality and physical properties of thin films.
4. Acquire the ability to accurately understand information obtained through the analysis of experimental data and to formulate rational research plans.
5. To develop the ability to communicate research results by presenting research results at laboratory meetings and at academic conferences in Japan.

Research activities will initially focus on thin-film synthesis equipment development, followed by thin-film synthesis and evaluation, and finally thin-film device development. In the thin-film synthesis system development, the research activities include equipment design, assembly of components, performance verification, repair and maintenance, and so on. In thin film synthesis and evaluation, inorganic compounds such as oxides, nitrides, and hydrides are synthesized according to the research theme of each student, and their film quality and physical properties are evaluated. Finally, through repeated synthesis and evaluation, highly functional thin films are realized. In the development of thin-film devices, we fabricate device structures by layering or processing originally developed thin films and evaluate their device characteristics. Finally, high-performance energy devices are realized through repeated device structure fabrication and characterization.

Evaluation will be based on a comprehensive evaluation of the student's daily research attitude, research results and other presentations at laboratory meetings, research achievements, conference presentations, and journal presentations. A total score of 60 points or more is considered acceptable.
