Titanium boosts thermoelectric performance of thin films by 250-fold

Every electronic device, factory and vehicle generates heat that often goes to waste. What if that energy could be recovered to generate electricity using thin films manufactured without high-temperature processing? Researchers at Tohoku University have taken a step toward making this possible, developing a thermoelectric material that delivers a 250-fold increase in power factor by adding a small amount of titanium to chromium nitride.
