Tl2GaCu3Se4
metal· JVASP-104673· Tl2GaCu3Se4
Tl2GaCu3Se4 is a quaternary chalcogenide compound combining thallium, gallium, copper, and selenium—a material class under active research for semiconductor and photovoltaic applications. This compound belongs to the family of ternary and quaternary metal chalcogenides, which are investigated for their tunable electronic and optical properties, particularly in contexts where bandgap engineering and light absorption are critical. While not yet mainstream in commercial production, materials of this compositional family show promise for next-generation thin-film photovoltaics, thermoelectrics, and optoelectronic devices where cost and performance trade-offs differ from conventional silicon or CdTe-based alternatives.
