Indium(III) selenide
open-in-new
<p>Indium(III) selenide is a compound of <a href="/facts/Indium/zRq3stVb">indium</a> and <a href="/facts/Selenium/k975NApC">selenium</a>. It has potential for use in <a href="/facts/Photovoltaic_effect/huqzdkH2">photovoltaic</a> devices and has been the subject of extensive research. The two most common phases, α and β, have a layered structure, while γ has a "defect <a href="/facts/Wurtzite_(crystal_structure)/dJLTu9SB">wurtzite structure</a>." In all, five <a href="/facts/Polymorphism_(materials_science)/bu2tqsB9">polymorphs</a> are known: α, β, γ, δ, κ. The α-β phase transition is accompanied by a change in electrical conductivity. The <a href="/facts/Band_gap/IjIeh95l">band gap</a> of γ-In2Se3 is approximately 1.9 eV. </p>
