摘要： Disclosed are chalcogenide nanomaterials, preferably metal chalcogenide nanomaterials, for example, copper, lead and/or silver chalcogenide nanomaterials. Also provided is a method or process of synthesizing or preparing a chalcogenide nanomaterial, preferably a metal chalcogenide nanomaterial. In an example, a wet-chemical method is used to prepare metal chalcogenide nanomaterials, preferably in a solvent and in the presence of one or more organic ligands. Another example method involves producing metal chalcogenide nanomaterial and includes the steps of forming a mixture of a metal precursor, a chalcogen-based ligand, a solvent and a chalcogen precursor, heating the mixture at a reaction temperature for a duration of reaction time, and separating a produced metal chalcogenide nanomaterial.

摘要： A process for manufacturing a nanocomposite thermoelectric material having a plurality of nanoparticle inclusions. The process includes determining a material composition to be investigated for the nanocomposite thermoelectric material, the material composition including a conductive bulk material and a nanoparticle material. In addition, a range of surface roughness values for the insulating nanoparticle material that can be obtained using current state of the art manufacturing techniques is determined. Thereafter, a plurality of Seebeck coefficients, electrical resistivity values, thermal conductivity values and figure of merit values as a function of the range of nanoparticle material surface roughness values is calculated. Based on these calculated values, a nanocomposite thermoelectric material composition or ranges of compositions is/are selected and manufactured.
