semiconductor· Sr2La2.58Bi5.42S14
Sr₂La₂.₅₈Bi₅.₄₂S₁₄ is a mixed-metal sulfide semiconductor compound combining strontium, lanthanum, and bismuth in a layered chalcogenide structure. This is a research-phase material belonging to the rare-earth bismuth sulfide family, synthesized for investigating novel semiconducting and optoelectronic properties rather than established industrial production. The compound's potential lies in solid-state applications where layered sulfide semiconductors show promise for thermoelectric energy conversion, photovoltaic devices, and radiation detection—areas where bismuth-containing chalcogenides offer tunable bandgaps and moderate carrier mobility without relying on toxic heavy metals like lead or cadmium.
