· Sn1Se0.75S0.25

Sn1Se0.75S0.25 is a mixed-anion tin chalcogenide semiconductor, a solid solution combining tin selenide (SnSe) and tin sulfide (SnS) in a 3:1 ratio. This compound belongs to the IV-VI semiconductor family and is primarily investigated in research settings for thermoelectric and optoelectronic applications, where the sulfur-selenium ratio is tuned to optimize band gap, phonon scattering, and carrier mobility. The partial substitution of selenium with sulfur modulates thermal and electrical transport properties compared to pure SnSe, making it relevant for mid-temperature thermoelectric power generation and potentially for photovoltaic or infrared sensing applications where bandgap engineering is critical.
