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.
Claims7
A process for producing an increase in figure of merit zT for a composite thermoelectric material to produce an enhanced composite thermoelectric material with the increased figure of merit zT, the process comprising mixing aerogel with the composite thermoelectric material, wherein the aerogel is formed from a material different than the composite thermoelectric material and the mixing further comprises ball milling the aerogel with the composite thermoelectric material.
