Copper selenide is an inorganic binary compound consisting of copper and selenium. Its formula is sometimes described as CuSe or Cu2Se. The crystalline structure and electronic behavior is determined by its elemental composition. Stoichiometric copper selenide is a zero bandgap material with metal-like behavior. Copper-deficient Cu2-xSe (non-stoichiometric) is an intrinsic p-type semiconductor with direct and indirect bandgap energies in the range of 2.1–2.3 eV and 1.2–1.4 eV, respectively. It is frequently grown as nanoparticles or other nanostructures.

  • Le séléniure de cuivre(I) est le séléniure de cuivre dans lequel le cuivre a le nombre d'oxydation +I, de formule théorique Cu2Se mais souvent non stœchiométrique (formule Cu2-xSe, où x est l'écart à la stœchiométrie). Il s'agit d'un matériau semi-conducteur. Il est souvent produit sous forme de nanoparticules. Le séléniure de cuivre est formé lors de certains traitements de bleuissage des aciers.
