Chemical compound
Copper selenide is an inorganic binary compound between copper and selenium. The chemical formula depends on the ratio between the two elements, such as CuSe or Cu2Se.
The crystalline structure and electronic behavior is determined by its elemental composition.[2] Stoichiometric copper selenide is a zero bandgap material with metal-like behavior.[3] 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.[4] It is frequently grown as nanoparticles or other nanostructures.[5][6][7]
