Transport properties of mechanochemically synthesized copper (I) selenide for potential applications in energy conversion and storage.

This work studied the thermal stability, electrical, and thermoelectrical properties of copper(I) selenide, CuSe synthesized by high-energy milling in a planetary ball mill. The phase composition was investigated by X-ray powder diffraction analysis and scanning electron microscopy. The conversion of the precursors during mechanochemical synthesis and the stability of the product was monitored by thermal analysis.
