The Thermoelectrics Design Laboratory (TE Design Lab) is devoted to accelerating the discovery and design of new thermoelectric materials. At the heart of such developments is a large body of accurate experimental and computational materials property data. The confluence of the database with data mining techniques and visualization tools enable discovery of targeted materials and identification of new structure-property relationships. Such functionalities elevate TE Design Lab from a simple data repository to a suite of thermoelectrics-focused tools.
