· Sr2Bi5.42La2.58S14

Sr2Bi5.42La2.58S14 is a mixed-metal sulfide semiconductor compound combining strontium, bismuth, and lanthanum in a layered crystal structure. This is a research-phase material studied for its potential as a photovoltaic absorber or optoelectronic component, belonging to the broader family of bismuth chalcogenides known for tunable bandgaps and layered electronic properties. The lanthanum doping strategy suggests investigation into band structure engineering for improved light absorption or charge carrier transport compared to undoped bismuth sulfides.
