Samarium Sulfide

Samarium sulfide is used as a sputtering target material to create thin films for studying pressure-induced semiconductor-to-metal phase transitions and piezoresistive sensors.

SmS is a unique semiconductor that undergoes a reversible valence transition and dramatic change in electrical conductivity under relatively low applied pressure.

As a rare earth chalcogenide, it is utilized in specialized electronic components that exploit the fluctuating valence states of the samarium ion.
