semiconductor· Ga1.7Cu0.3S2.7
Ga₁.₇Cu₀.₃S₂.₇ is a quaternary semiconductor compound combining gallium, copper, and sulfur in a non-stoichiometric ratio, belonging to the family of I-III-VI₂ chalcogenides. This material is primarily investigated in research settings for photovoltaic and optoelectronic applications, where its tunable bandgap and mixed-valence chemistry offer potential advantages over conventional binary semiconductors like CdS or GaAs, particularly for thin-film solar cells and light-emission devices where cost and compositional flexibility are priorities.
