Attention is attracting attention for the next -generation heat control and unused heat in semiconductors. By realizing a sensor node equipped with a thermoelectric environmental power generation device, you can set up a huge number of energy -to -independent sensors in society and connect physical space and cyber space essential for smart socialization. In this laboratory, we are conducting research that dramatically enhances thermoelectric conversion ability by forming nano processing in low -environmental silicon materials. He has been conducting joint research with Freiburg University in Germany and many companies, and has been reported in the Nikkei Sangyo Shimbun as a new device application.

We have studied ballistic phonnics and thermal phonnics using the trajectory and wave properties of the phonnon, which are remarkably expressed in nanoscale, and discover and develop high -flow control and thermal conduction control technology that cannot be realized by the conventional Fourer rules. We observe characteristic thermal conduction physics that emerges in nanoscale by a unique micro -time area thermal reflection measurement method using pulse laser. For the first time in the world, the company succeeded in producing orthodox thermal flow and solid thermal collecting using the ballistic properties of the phonon, and brought a new development to thermal engineering.
