Helping Devices Take the Heat

A new class of organic conductors shows high thermoelectric efficiency, thanks to an unusual arrangement of electrons inside its bonds.

Together with Shuo-Wang Yang at A*STAR's Institute of High Performance Computing (IHPC), Jianwei Xu and Dexter Tam, scientists at the A*STAR Institute of Materials Research and Engineering (IMRE) have showed how these rapid switches also occasionally separate the tightly-bound pairs of electrons that make up chemical bonds.

“Our findings provide design strategies to improve both conductivity and Seebeck coefficient simultaneously for thermoelectric applications,” Tam said, adding that they hope to further explore the application of proquinoidal polymers in spintronics and thin-film soft magnets.
