    Synthesis and Thermoelectric Properties of Copper

    Large-scale Cu2S tetradecahedrons microcrystals and sheet-like Cu2S nanocrystals were synthesized by employing a hydrothermal synthesis HS method and wet chemistry method WCM, respectively. The morphology of -Cu2S powders prepared by the HS method is a tetradecahedron with the size of 17 m. The morphology of -Cu2S is a hexagonal sheet-like structure with a thickness of 520 nm.
