  • Method for preparing and use of SbTe nanocrystals in thermoelectric materials
    Patent number: 9209374
    Abstract: 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.
    Type: Grant
    Filed: March 25, 2013
    Date of Patent: December 8, 2015
    Assignee: Evident Technologies, Inc.
    Inventors: Adam Z. Peng, Susanthri Perera, Dave Socha, Clinton T. Ballinger
