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.
