Germanium monosulfide or Germanium(II) sulfide is the chemical compound with the formula Ge S. It is a chalcogenide glass and a semiconductor . [ 1 ] Germanium sulfide is described as a red-brown powder or black crystals. [ 2 ]
Germanium sulfide may refer to: Germanium(IV) sulfide GeS 2 , also known as Germanium disulfide Germanium(II) sulfide GeS, a semiconductor also known as Germanium monosulfide
Two oxides of germanium are known: germanium dioxide (GeO 2, germania) and germanium monoxide, (GeO). [4] The dioxide, GeO 2 can be obtained by roasting germanium disulfide (GeS 2) or by allowing elemental germanium to slowly oxidze in air, [5] and is a white powder that is only slightly soluble in water but reacts with alkalis to form germanates.

Pure germanium is known to spontaneously extrude very long screw dislocations, referred to as germanium whiskers. The growth of these whiskers is one of the primary reasons for the failure of older diodes and transistors made from germanium, as, depending on what they eventually touch, they may lead to an electrical short .
