Samarium monosulfide forms crystals ofcubic system, spatial groupFm3m, cell parameters a = 0.5970–0.5863 nm, Z = 4, structurally isomorphic with NaCl.[2]
The compound melts congruently at a temperature of 1500 °C, 1940 °C, or 2080 °C.[3]
SmS is a chalcogenide material that exists in two possible states: as a metal (also called "golden") and as asemiconductor ("blue" or "black").[4] As a result, SmS has gained considerable interest as a switchable material.[5]
Samarium monosulfide has a high sensitivity to deformation. Therefore, SmS is a promising material for creating pressure sensors of force, torque, accelerations, etc.[6]
