properties

Indium (III) selenide is a black, fairly soft solid that is easily soluble in strong acids . In total, five different forms of indium (III) selenide are known, which are referred to as α-, β-, γ-, δ-, κ-. The two most widespread forms α- and β- have a wurtzite structure with vacancies in the cation lattice. The band gap of γ-In ₂ Se ₃ is approximately 1.9 eV .
