Development of functional materials leading to sustainable low-carbon society

In the Energy Materials Laboratory, we develop functional materials, such as thermoelectric materials, thermal diodes, and high-Tc superconductors. These materials lead to low sustainable low-carbon society. For these studies, we are using detailed analyses on electronic structure both from experiments and theoretical calculations.

Research Themes

Development of high performance thermoelectric materials using solely of ubiquitous elements

Development of thermal rectifier usable at high temperatures

Investigation into the origin of high critical temperature of curate superconductor
