Evaluation of the characteristics of a new alloy CoPtN that is designed to enhance spin polarization of Pt according to AI-derived knowledge confirmed that thermoelectric conversion efficiency around 100 times higher than that of previous Pt alloy was obtained.
"We will continue to further expand the search for materials using AI in the future, focusing on further improvement in the thermoelectric conversion efficiency of spin-current thermoelectric conversion elements and the development of new low-cost materials," said Eiji Saitoh, Professor, Tohoku University.
"We aim for the early pranctical application of spin-current thermoelectric conversion elements as power source technology for IoT devices that will continue to work for years without a battery or other power source and as low cost, high performance electronic cooling technology," said Soichi Tsumura, General Manager, NEC IoT Devices Research Laboratories.
