Copper Selenide Nanoparticles

Copper Selenide Nanoparticles

Copper selenide nanoparticles are a class of copper-based compounds in which copper is combined with selenium. Cu₂Se is a semiconductor material with unique electronic, optical, and thermoelectric properties. Copper selenide exists in several polymorphs, with copper selenide (Cu₂Se) being the most stable and widely studied. Copper selenide nanoparticles are characterized by their distinctive crystalline structure, size, and morphology, which can be tailored for specific applications.

Cu₂Se is known for its n-type or p-type semiconducting behavior, depending on its composition and doping, and it exhibits good electrical conductivity and thermal stability. It is of particular interest due to its thermoelectric properties, which make it useful in converting heat into electrical energy. Additionally, show promise in photovoltaic, catalytic, and energy storage applications.
