Germanium monosulfide or Germanium(II) sulfide is the chemical compound with the formula GeS. It is a chalcogenide glass and a semiconductor.[1] Germanium sulfide is described as a red-brown powder or black crystals.[2] Germanium(II) sulfide when dry is stable in air, hydrolyzes slowly in moist air but rapidly reacts in water forming Ge(OH)2 and then GeO.[3] It is one of a few sulfides that can be sublimed under vacuum without decomposition.[4]
