semiconductor· In1.1Cu0.9Se2.1
In₁.₁Cu₀.₉Se₂.₁ is a quaternary semiconductor compound combining indium, copper, and selenium in a near-stoichiometric ratio, belonging to the I-III-VI₂ family of ternary and quaternary semiconductors. This material is primarily investigated in research contexts for photovoltaic and optoelectronic applications, where tunable bandgap and improved carrier transport are sought relative to binary or simpler ternary alternatives. The copper-indium selenide base system offers potential for thin-film solar cells and light-emitting devices due to its direct bandgap properties and defect-tolerant crystal structure.
