Indium(III) Selenide Pellet Evaporation Material (In2Se3)

Indium(III) selenide is a compound of indium and selenium. It has potential for use in photovoltaic devices, and it has been the subject of extensive research. The two most common phases, α, and β, have a layered structure, while γ is a "defect wurtzite structure." In all, there are five known forms (α, β, γ, δ, κ). The change in electrical conductivity accompanies α-β phase transition. The band-gap of γ-In2Se3 is approximately 1.9 eV. The crystalline form of a sample can depend on the production method. For example, thin films of pure γ-In2Se3 have been produced from trimethylindium (InMe3) and hydrogen selenide (H2Se) using MOCVD techniques.
