General description

Indium selenide (In2Se3) exists in 4 crystal structures (α,β,δ,γ).The metallic α-phase of indium selenide converts to intrinsic conduction β-phase under change in temperature. In2Se3 can be prepared by stoichiometric combination of the elements at 1000 to 1100oC temperatures. Influence of phase transformations on its optical and electrical properties has been reported.[1]
