  • Apparatus and method for enhancing figure of merit in composite thermoelectric materials with aerogel
    Patent number: 11107963
    Abstract: At least one of the present embodiments generally relates to an apparatus and a method for enhancing the figure of merit (zT) in composite thermoelectric materials using aerogel such as e.g., silicate/silica aerogel, carbon aerogel, chalcogenide aerogel and metal oxide aerogel. For example, the present embodiments provide apparatuses and methods for the addition of aerogels to two commonly used p and n type thermoelectric materials and thereby enhancing their thermoelectric figure of merits to record levels.

  • Thermoelectric alloy, method for producing the same and thermoelectric alloy composite
    Patent number: 10975456
    Abstract: The present invention relates to a thermoelectric alloy and a method for producing the same. A starting material is firstly provided, and an oxidation process is performed to the starting material to obtain an oxidized material composition. Then, the oxidized material composition and a carburizing agent are added into a quartz tube, and a sealing process is performed to the quartz tube. And then, the sealed quartz tube is subjected to a carburization process, thereby obtaining the thermoelectric alloy with excellent thermoelectric figure-of-merit.
