US Patent 9209374 Method for preparing and use of Sb

Disclosed are a thermoelectric material and a method of forming a thermoelectric material having an optimal stoichiometry, the method including obtaining a first precursor material, wherein the first precursor material is an antimony precursor, and obtaining a second precursor material, wherein the second precursor is chosen from the group consisting of a tellurium precursor and a selenium precursor. The method further includes combining the precursor materials, heating the combination of precursor materials, and isolating a plurality of semiconductor nanocrystals from the heated precursor materials.
